<html><head></head><body><div>I am trying to use dovecot without ssl in centos 7. It works with imap but I am not able to make it work with pop3. Pop3 only works with ssl=yes. I can use dovecot in centos 4 ok. I get the same error with thunderbird and outlook. But for some reason it works when I telnet to port 110 and do retr 1. I was able to work pam and shadow passwords.</div><div><br></div><div>this is the output that does not work with tls disabled</div><div><br></div><div><span><div>Oct 18 13:30:17 auth: Debug: Loading
