I have (or had) a working setup of mailcow. Since 2 weeks ago I’m unable to send emails. Mails arrive, but not depart.
From logs of postfix container:
The service tries to find
sni.map.db file and fails.
So far I’ve tried:
mailcow.conf was like this:
then I’ve tried to change it, assigning
ENABLE_SSL_SNI=y, ADDITIONAL_SAN=mail.*,smtp.*,imap.*, SKIP_LETS_ENCRYPT=y in different combinations (yes, no, etc), but no luck.
Also updated the mailcow with update.sh script, stopped and restarted containers, even upgraded debian to bullseye from previous one, still not working.
Could someone please help me with it?
