Now I am getting “ERR Authentication failed” while sending mail using pop3 account.

# telnet localhost pop3
Trying ::1...
Connected to localhost.
Escape character is '^]'.
+OK Dovecot ready.

We need more information. Change /etc/dovecot/dovecot.conf:
Code:
auth_verbose = yes
and while you're in that file check where dovecot is logging. It could be /var/log/mail. Reload dovecot by using your distro's method or alternatively send it a HUP signal.

Try using telnet again and reply here with the relevant lines from the log.

It is as simple as it says authentication fails. With the settings you mention the easiest way to check is to type saslfinger -c and it will tell you what to do. My guess is that you did not set up sasl properly or there is no authentication provided, in other words there is no passwd file to take your authentication data from.

Thanks for that. Somehow, I've managed to configure many postfix installs without coming across it.

That means you have never tried sending emails from other networks. Postfix will never allow you do so unless you are properly authenticated. I travel a lot and connect from different networks (even within my city limits' various wifis for example) therefore I can send my email from any IP addresses and absolutely any machines and networks in the world. My silly ISP which happens to be a big serious company does not use any SMTP authentication at all as well despite the fact that they have millions of users.. so.. not using it at all is not new, it's just having your users think that something is not working somewhere or having the users leave in searches for smarter providers that consider and provide all the flexibility of the options...
