netstat -la -pute | grep dovecot

I dont like the "port = 0"  but thats what was mentionned in the tutorial


so I changed /etc/dovecot/conf.d/10-master.conf
/

service imap-login {
  inet_listener imap {
    port = 143
  }
...
}

service pop3-login {
  inet_listener pop3 {
    port = 110
  }
...
}


now

netstat -la -pute | grep dovecot

I think the issue is with authentication

There is "no auth attempts", so you do not have an issue with authentication.

Because of the "TLS handshaking: Disconnected" it looks like the connection gets cut during the initial TLS handshake. To debug this, first increare logging, then try from localhost without encryption, e.g.:

telnet localhost 143
1 login "loginname" "password"

and watch the human friendly output. Terminate the IMAP connection via

2 logout

Maybe that client does not like your SSL cert and drops the connection thereof? Or maybe a firewall thinks it has to fiddle in, e.g. change Thunderbird to use SSL on port 993 instead of STARTTLS on 143.

Kind regards,
