Patching qmail


The complete changelog is inside the patch file.

  • 2014-11-20
    -the SSLv3 connection upon the auth was switched off because of security reasons (thanks to Florian)
  • 2014-11-15
    -modified the QUEUE_EXTRA variable in extra.h to record the Message-ID in the qmail-send's log. Thanks to Simone for the hint.
  • 2014-04-14
    -added qmail-maxrcpt patch, which allows you to set a limit on how many recipients are specified
  • 2014-03-10
    -added qmail-smtpd-liberal-lf patch, which allows qmail-smtpd to accept messages that are terminated with a single \n instead of the required \r\n sequence. This should avoid some "read failed" reject.
  • 2013-12-30
    -added qmail-SRS patch. You have to install libsrs2 now.

    any-to-cname patch added

I have created a combined patch including the latest versions of several commonly-used qmail patches:

[Follow the patch details here]

Other patches:

You're invited to take a look at the next page of this guide, which presents several tests for these patches toward the bottom of the page.

NB: first of all, you must have a valid MX record for you /var/qmail/control/me domain, otherwise you''ll get errors when trying to send to ~alias/qmail-log (more info here).

Installing libdomainkeys

This library is a prerequisite of the DKIM patch by Manvendra Bhangui, which is part of my package. You must compile this, otherwise the compilation will break.

cd /usr/local/src
tar xzf libdomainkeys-0.69.tar.gz
ln -s libdomainkeys-0.69 libdomainkeys
cd libdomainkeys
chown -R root.root .
patch < ../libdomainkeys-0.69.diff
cd ../

Installing libsrs2

This library is a prerequisite of the SRS patch, which is part of my package. You must install this, otherwise the compilation will break.

tar xzf libsrs2-1.0.18.tar.gz
cd libsrs2-1.0.18
make install
cd ../

Be sure that libsrs2 is actually linked, otherwise you are going to have a qmail-send infinite crash and finally an auto-DoS:

> ldconfig -p|grep libsrs2 (libc6,x86-64) => /usr/local/lib/ (libc6,x86-64) => /usr/local/lib/

In case you decided to install the libsrs2 library by means of a package provided by your Linux distribution, you should check the path where the library was installed. Check if the file /usr/local/include/srs2.h actually exists; if not you may have to modify the srs.c in the netqmail source dir as follows:

#include </usr/local/include/srs2.h>
#include </usr/include/srs2.h>

Apply the patch

cd netqmail-1.06
gunzip -c ../roberto-netqmail-1.06.patch-latest.gz | patch

Configuring chkuser

The combined patch you downloaded has chkuser enabled. It’s configured to perform recipient verification and MAV (Mail From: Address Verification). 

You can customize your configuration by editing the chkuser_settings.h file (in /usr/local/src/netqmail-1.06) before compiling qmail. In order to enable chkuser, the following line must be commented out:


Uncomment to enable the check of user and domain format for sender address. This will reject fake senders without any domain declared (like <foo>).


Uncomment to enable checking of domain MX for rcpt addresses


Uncomment to enable checking of domain MX for sender address


This enables usage of "#" and "+" characters within sender address. It is used by SRS (Sender Rewriting Scheme) products.

As far as my MTA Is concerned, this solved an "invalid sender address format" reject message prompted by an email address of a mailman mailing list..


force-tls variables

By default the authentication will be denied if the client does not provide the STARTTLS command. If you want to allow connections without TLS, just do

export FORCETLS=0

in your run file. Values other than 0 (or not declaring this variable at all) will force TLS before the auth.

qmail-auth variables

By default the auth is allowed with LOGIN or PLAIN mechanism. You are invited to look at the README.auth file for further details concerning the use of the SMTPAUTH environment variable, expecially if you want to use CRAM-MD5.

Recompiling qmail

The BIG-TODO patch included in my combined patch may require that your queue be rebuilt. So be aware that all existing messages in the queue will be destroyed when you erase the queue below.

To discover if your qmail has messages in the queue:

> qmailctl stat

/service/qmail-send: up (pid 18127) 6 seconds
/service/qmail-send/log: up (pid 18134) 6 seconds
/service/qmail-smtpd: up (pid 18126) 6 seconds
/service/qmail-smtpd/log: up (pid 18135) 6 seconds
/service/qmail-submission: up (pid 18131) 6 seconds
/service/qmail-submission/log: up (pid 18132) 6 seconds
/service/vpopmaild: up (pid 18129) 6 seconds
/service/vpopmaild/log: up (pid 18128) 6 seconds
messages in queue: 0
messages in queue but not yet preprocessed: 0

If this will be the first time you install the combined patch (which contains the BIG-TODO patch), you’ll need to take these steps:

qmailctl stop
rm -r /var/qmail/queue

Now compile qmail:


If qmail is running stop the services before installing:

qmailctl stop

Finally install and start  qmail:

make setup check
qmailctl start

Creating an SSL key file

If you don’t want to enable SMTP relay (using SMTP/TLS access), you can skip this section.

To secure the smtp authentication you must create the SSL certificate. The certificate must be owned by the user who runs qmail-smtpd, in our case vpopmail.

> make cert

Generating a 1024 bit RSA private key
writing new private key to '/var/qmail/control/servercert.pem'
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
Country Name (2 letter code) [AU]:IT
State or Province Name (full name) [Some-State]:Italy
Locality Name (eg, city) []:Cagliari
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Your Name
Organizational Unit Name (eg, section) []:
Common Name (eg, YOUR name) []
Email Address []

> make tmprsadh
> chown vpopmail.vchkpw /var/qmail/control/*.pem

It is important that the “Common Name” matches the domain name that your email clients will specify as their SMTP server.

Now let’s create a cronjob to update the certificate every day:

> crontab -e

03 05 * * * /var/qmail/bin/update_tmprsadh > /dev/null 2>&1

Important: If you run qmail-submission as a user other than vpopmail, and you’re installing my combined patch, you must adjust /var/qmail/bin/update_tmprsadh accordingly. Otherwise you’ll probably exceed the connection timeout due to privilege problems, and won’t be able to send messages when connected remotely.

Combined patch details


It provides cram-md5, login, plain authentication support for qmail-smtpd (port 587) and qmail-remote.


It implements SSL or TLS encrypted and authenticated SMTP between the MTAs and from MUA to MTA. I have adjusted the file update_tmprsadh to chown the .pem files to vpopmail, which runs qmail-smtpd.
The SSLv3 connection was switched off because of security reasons (thanks to Florian).

You may be interested to take a look to the page concerning smtp-auth and TLS testing here.


optionally gets qmail to require TLS before authentication to improve security.


performs recipient verification and Mail From: Address Verification (MAV).

You may be interested to take a look to this page concerning chkuser testing.


Enables simscan and qmail-dkim to return the appropriate message for each e-mail it refuses to deliver. Simscan rejects with the name of the virus or the spam-score; qmail-dkim rejects with the verification failure message.


  • Author: Christophe Saout. Patch modified by Manvendra Bhangui to make it IPv4-mapped IPv6 addresses compliant.
  • Info:
  • Version rc5

It can check incoming mails inside the SMTP daemon, add Received-SPF lines and optionally block undesired transfers.


implements Sender Rewriting Scheme fixing SPF break upon email forwarding. To enable SRS read carefully the configuration instructions above.

Oversize DNS

This patch enables qmail to handle large DNS packets.

Reread concurrency patch

rereads control/concurrencylocal and control/concurrencyremote files when qmail-send receives a HUP signal.

Big Concurrency patch

It sets the spawn limit above 255.

Big Concurrency fix

Fixes a compiler error if you set concurrency higher than 509 in /usr/local/src/netqmail-1.06/conf-spawn.

maildir++ patch

adds maildirquota support to qmail-pop3d and qmail-local.

Better qmail-smtpd Logging patch

Facilitates diagnosing qmail-smtpd logging its actions and decisions (search for a line starting with qmail-smtp:). This is useful for discovering fake IP addresses with bad HELO’s when qmail-smtpd doesn’t log anything.

Greeting delay patch

  • Author: John Simpson (?)
  • Download here
  • More info here

adds a user-definable delay after SMTP clients have initiated SMTP sessions, prior to qmail-smtpd responding with "220 ESMTP". It can reject connections from clients which tried to send commands before greeting. You can control the delay via the environment variable SMTPD_GREETDELAY (was GREETDELAY in the original patch). A value of SMTPD_GREETDELAY=”30” will delay qmail-smtpd’s response for 30 seconds.

DKIM and SURBL patch

adds DKIM signing & verification support to qmail at both qmail-smtpd and qmail-remote/local level and SURBL filtering support to qmail.  
The file hier.c modified to chown /var/qmail/control/cache and subdirs to vpopmail.

EXT-TODO patch

addresses a problem known as the silly qmail (queue)  problem.

BIG-TODO patch

Makes qmail use a hashing mechanism in the todo folder similar to that used in the rest of the queue.

qmail-inject-null-sender patch

Prevents qmail-inject from rewriting the null sender, fixing an issue with sieve vacation/reject messages.

doublebounce-trim patch

Prevents double bounces from hitting your queue a second time provided that you delete the first line from /var/qmail/control/doublebounceto

esmtp-size patch

Enables qmail-smtpd to reject messages if they’re larger than the maximum number of bytes allowed (you can set this value in the /var/qmail/control/databytes control file).


Provides the ability to archive each email that flows through the system.

qmail-remote CRLF patch

Enables qmail-remote to handle CR (\r) properly, always sending the line breaks as CRLF (\r\n) and avoiding to double the CR (like qmail-remote normally does). This often caused me a broken header when forwarding messages by means of a sieve rule.

outgoingip patch

  • Author: Andy Repton (adjusted by Sergio Gelato)
  • Original patch:
  • Robbie Walker provided a patch to correct qmail-qmqpc.c's call to timeoutconn(), because the function signature was modified by the original outgoingip patch

By default all outgoing emails are sent through the first IP address on the interface. In case of a multiple IP server this patch makes qmail send outgoing emails with the IP eventually stored in control/outgoingip. The ehlo domain is NOT modified by this patch.

qmail-bounce patch

limits the size of bounces. The default limit for bounces is 50000 bytes, but you can create a file in crontrol/bouncemaxbytes in order to change that number.

qmail-smtpd pid, qp log patch

makes qmail-smtpd log a line similar to the following:

@4000000039b89c95026a89b4 mail recv: pid 8155 from <name@domain.xy> qp 8157

The pid allows you to match the message up with a given tcpserver process and the qp lets you find a particular delivery.


avoids qmail getting large amounts of DNS data we have no interest in and that may overflow our response  buffer.

qmail-rfc2821 patch

makes qmail rfc2821 compliant

smtpd-502-to-500 patch

  • Author: Jonathan de Boyne Pollard
  • Original patch: local copy
  • More info here

makes qmail rfc2821 compliant

qmail-dnsbl patch

allows you to reject spam and virus looking at the sender's ip address. Added a line to make qmail-smtpd log the reject reason as well as the envelope to facilitate diagnostics.

qmail-moreipme patch

prevents a problem caused by an MX or other mail routing directive instructing qmail to connect to itself without realizing it's connecting to itself, saving CPU time.


  • Author: Alex Nee
  • Download here

It will hide your Private or Public IP in the email Headers when you are sending Mail as a Relay Client.

qmail-date-localtime patch

  • Author: John Saunders
  • Download here

causes the various qmail programs to generate date stamps in the local timezone.

qmail-liberal-lf patch

allows qmail-smtpd to accept messages that are terminated with a single \n instead of the required \r\n  sequence.


allows you to set a limit on how many recipients are specified for any one email message by setting control/maxrcpt. RFC 2821 section says that an MTA MUST allow at least 100 recipients for each message, since this is one of the favourite tricks of the spammer.
I slightly modified the patch also to log its response.


I modified extra.h to record the Message-ID in the qmail-send log as explained here towards the bottom of the page. An alias ~alias/.qmail-log had to be added as well to store the awk command with the regex which retrieves the Message-ID.
Thanks to Simone for the hint.

Be aware that you must have a valid MX record for your FQDN (look at /var/qmail/control/me).

The qmail-send log now appears as follows:

qmail-smtpd: read failed: (null) only with one sender

Hello Roberto,

i have a problem with mails coming from amazon. Every Mail send from amazon is not delivered because it shows the error qmail-smtpd: read failed. This error only happen with mails from the amazon mail servers, i do not have this eror with other mails. I have no clue whats wrong -  do you have an idea? Output from Log File:

qmail-smtpd read failed - SPF Check was the problem

Hello Roberto,

thanks for the hint with recordio. I figured out that the SPF check was the problem:

@4000000054a81075289ded24 9091 > 451 SPF lookup failure (#4.3.0)
@4000000054a8107529ddac9c 9091 < RSET
@4000000054a8107529de0674 9091 > 250 flushed

When i changed the /var/qmail/control/spfbehavior entry to 1 mail from amazon get thru and i noticed, that it take some time to process the mail.

I tried a manual spfquery for the amazon mail and the check take about 70 sec. So i think that the check takes to long and the qmail-smtp process take this as an timeout and reject the mail because of that. Other spf checks to other domains are working fast. Maybe i should try to change the dns server entry? But it is strange that this happens only to amazon servers.

Thanks for helping.

  I would try a test

I would try a test like

dig txt

and see if you get a timeout error or not

So I delete the domain and re-add, now it can deliver to local account.

Hi Roberto ,

I have followed your excellent guide and installed my server. The issues is for every mail that is sent or received it is trying to send a copy to some log alias. How can I disable that . Below is the message transcript.

anyway I think you have deleted the ~alias/.qmail-log alias or you don't have a valid mx for your control/me domain. Actually this is not a real mailbox but an alias created in order to improve the qmail-send log, so you may want to continue to use it

qmail-log alias

ahhh now I get you , actually this is a newly created server and I have still not pointed the mx to the new servers ip . Let me check by doing point the valid MX to the server .

dovecot issue?

It can be a dovecot issue (you should also look for dovecot-lda errors, expecially in the sql driver).

But it's strange that you can't have it working when using vpopmail as deliver. Are there any .qmail overriding the defaultdelivery?

Let's fix vpopmail first of all.

I've change the

DKIM and SRS = fail :-(


if you use SRS, DKIM filter fails, as it sets original SENDER domain instead of that specified in SRS. Any suggestions how to fix it?

cheers and thanks for your patches!


Can you post how the headers

Can you post how the headers look like when we you use SRS?

I contacted M.Banghui, the author of the DKIM patch, and he told me that he can fix it.

Sure :)

The DKIM is getting _SENDER  - and SRS is providing to qmail an original Sender domain, instead of the one taken from /var/qmail/control/srs_domain

BTW, why don't you move your awesome patchset to github? It would make things much easier :)

I would declare I can work on IPv6 part, as it is the only (but big) missing thing from your patches.



Hi, can you do a cut&paste of

Hi, can you do a cut&paste of the headers?

Actually an help on the IPv6 patch would be appreciated, as I have not much time these days, and I'm not an IPv6 expert. As you probably know M.Banghui has merged an IPv6 patch in his DKIM/SURBL and my plan is to add it to my package soon or later :)

qmail-todo problem

Firslty, thanks Roberto for ur efforts of creating the patch, But i'm facing a critical problem after i patched qmail 1.6  with ur patch that i have found my server load reached to 250, and when i check the process found that qmail-todo consuming cpu terribly. But i don't know why this happened and what should i do, although i have applied the steps and installed qmail successfully.

Re: qmail-todo problem

Hi Kamal,

I assume that you erased your queue in this way before installing the todo-patched qmail for the first time:

qmailctl stop
rm -rf /var/qmail/queue
make setup check

If yes please post a

ps axfuww | grep qmail 

The best way to investigate what qmail-todo is doing is using strace:

strace -Ff -o /tmp/qmail-strace.log -p <pid_of_qmail-todo>

Re: qmail-todo problem

Hi Roberto,

Yes, I already erased the queue as you mentioned, I want to clear something i'm using the combined patch "roberto-netqmail1.06.patch-latest"  NOT todo-patch. but the problem with qmail-todo process that was consuming cpu.

Kindly find output details below,



Maybe a lbsrs problem did you

Maybe a lbsrs problem did you successfully installed it? did you ldconfig it?

I think it's not a libsrs

I think it's not a libsrs issue, as in that case the compilation itself will break

Re: qmail-todo problem

it seems to be an infinite loop...

when you stop qmail I would try to kill all those qmail-todo which doesn't belong to qmail-send anymore, and after that erase the existing queue, recompile and restart qmail

Re: qmail-todo problem

I realy did that, but unfortunately still the same, the load reached to 270,and server was going to explode.
