Hello!
Dovecot manages different domains. Today I renewed the certifiactes from letsencrypt and since that time, dovecot does not recognized the certs for different domains anymore:
This is part of my config:
ssl = yes ssl_cert = < /etc/letsencrypt/live/bitcorner.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/bitcorner.de/privkey.pem
local 37.120.166.21 { # instead of IP you can also use hostname, which will be resolved protocol imap { ssl_cert = < /etc/letsencrypt/live/bitcorner.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/bitcorner.de/privkey.pem } }
local 46.38.231.143 { protocol imap { ssl_cert = < /etc/letsencrypt/live/nimmini.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/nimmini.de/privkey.pem } }
This worked for years and I don't know what's wrong now. It seems dovecot just takes the default certs into account and ignores the certs defined with "local" completly.
Any help appreciated.
Kind regards
Andreas

What problem are you seeing? It uses the correct SSL certs when I connect.

Thank you for your investigation! It turned out there was a problem on the server with IPv6 binding to the wrong virtual network-interface.
Everthing's running smoothly so far although there is still a problem adding the right IPv6-address additionally to the IPv4-address.
Kind regards
Andreas
