I'd love to use this port, the autoinstaller even adds this port to the firewall if you want to install it. I can't see any mention in the postfix config files, though, is this a wanted behaviour? As far as I know, Outlook clients still need that port? Cheers
That's because it has been renamed, it is now called submissions (with s, not to mix up with submission which is port 587). And the renaming is also the reason why the auto installer did not enable it. See manual install instructions on how to enable it: https://www.howtoforge.com/perfect-server-debian-12-buster-apache-bind-dovecot-ispconfig-3-2/ No. But it has been fixed and will be part of the next release of the auto installer.
