On december 2017 dovecot-2.3.0 was released. As far as my previous 2.2 configuration is concerned, there are just a few changes:
- the submission service can be disabled (just rename
20-submission.conf); - if you were using the maildir++ patch for netqmail embedded in my combined patch, you have to add "
maildir_broken_filename_sizes = yes" in your10-mail.conf(tx MG). This parameter is not needed if you restored the maildirs as explained above; - changes in
10-ssl.conf: you have to setup a SSL DH parameter and replace some other obsolete parameter; take a look to the dovecot page for more info; - changes in
15-lda.conf: thesendmailprogram was not working anymore here when called bymanagesieve. So we can disable it and setup asubmission_host(not to be confused with the submission service above); - some change in both
20-managesieve.confand90-sieve.conf: it's better to rebuild them from scratch following this page.
