Yes, Dovecot should be listening on port 587 if using "submission" service After I read that I tried uncommenting the submission line in master.cf but then Postfix wouldn't start so I commented it out again and restarted Postfix The last of these problems doesn't show in the log just Thunderbird says it couldn't connect to the relay server and I should check to make sure my email address is correct On Sun, Jan 12, 2025 at 6:06 PM Tomasz Pala via Postfix-users < postfix-users@postfix.org> wrote: > On 2025-01-12 20:59, Scott K via Postfix-users wrote: > > Postfix with Dovecot which should be listening on port 587? > > Let your admin decide, both require a lot of understanding and > configuration to match system requirements. > Both have comprehensive docs, covering most important aspects > (SASL/AUTH, subsystems, milters, sieves etc.) > > If you start SMTP server before you're familiar with that you'll > probably end up being open relay harming yourself and entire net, > so until you're ready just keep you firewall selective. > ___ > Postfix-users mailing list -- postfix-users@postfix.org > To unsubscribe send an email to postfix-users-le...@postfix.org > ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

[pfx] Re: Postfix with Dovecot which should be listening on port 587?
So after I disable Dovecot submission (by renaming /etc/dovecot/protocols.d/submissiond.protocol to submission.protocol.renamed) will Postfix then listen on 587 automatically? It was previously said that Dovecot was listening on 587 and Postfix listening on 25 On Tue, Jan 14, 2025 at 1:59 AM Tomasz Pala via Postfix-users < postfix-users@postfix.org> wrote: > On 2025-01-14 05:38, Peter via Postfix-users wrote: > > > > Dovecot submission is just a proxy, it still has to pass the submitted > > message to postfix so there is little reason to use dovecot submission > > unless you need BURL support.
