I reinstalled Dovecot this evening, because I haven't been able to receive emails recently. After configuring and adjusting for the use of PostfixAdmin, I get the following error message in Evolution:;
Failed to open folder. The reported error was "Failed to authenticate: TLS connection closed unexpectedly".
Does anyone recognize this error? Do you have a connection attempt logged by dovecot? Is there anything in the logs on the server?
Here's the output of tail /var/log/mail.log:
