Hi all, I got in my phone a warning that can't verify ssl and is not retrieving emails anymore. I logged in to the server and saw that the ssl is still valid (letsencrypt). acme reports that needs renewing in a month or so. I haven't done any change from my side. How can I troubleshoot this? Imap is dovecot.
Applications do not pick up new or updated SSL certs on their own, they need to be restarted for that. For some reason, dovecot was apparently not restarted after the SSL cert was renewed, maybe it was renewed manually and not by ISPConfig, and therefore dovecot did not used the new updated cert.
