Can someone please explain to me how should I configure mail / domain to match let’s encrypt mail certificate?
On domain configuration I have:
MX record mail.domain.com
A record *.domain.com to IP
Virtualmin hosts does have alias with mail.domain.com and lets’s encrypt certificate for this alias.
Now when try to configure external email client like Thunderbird it discovers mail.domain.com and ports but certificate matches completely different domain on my server? How to match certificates for each domain?
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
you need to add domain certificate to postfix.
Webmin → Servers → Postfix → Certificate Mapping.
add a map (eg. hash:/etc/postfix/sni_map) and then add records for each domain…
name as mail.domain, which maps to your certificate+key files path.
you can find examples online, maybe in this forum too.
I have a clue I had imported virtualhost with same name:
which caused first one to create directory domainameeu and rearnage all configs. When configuring email account it ponts to domainame.host.com for some reason. Probably not all configs where ammended. Also can’t copy SSL certificate to deovecot within: domainame.eu
