Grommunio IMAP SSL Issue

Ttobiasgoeller · 2025-03-29T13:26:27+00:00

All,

I am trying to get imaps to work - no cigar so far. I am pretty sure I overlooked something... but if I look at the documentation, some flags like imap_support_ssl seem to be undocumented there... - I am currently a bit out of ideas.

#listen_port=143
listen_ssl_port=993
imap_support_ssl=yes
imap_force_starttls=true
imap_certificate_path=/etc/gromox/ssl/fullchain.pem
imap_private_key_path=/etc/gromox/ssl/privkey.pem
default_domain=my.domain.org

it starts on port 143 - but it's not doing anything on 993 (no listen, no nothing).

It's a debian 12 installation - which might be a bit an issue (but I don't like to have another distro running here - and I'm not a huge fan of opensuse)

Any idea what's going wrong?

Status seems to be OK (and I have checked, I can connect using port 143)

systemctl status gromox-imap.service

This is my imap.cfg and my IMAP works.

imap_certificate_path=/etc/grommunio-common/ssl/server-bundle.pem
