Dovecot pop3 authentication problem
 

I'm having problems authenticating against my Dovecot pop3 server.
When I look at the mail.log file here is my output.

dovecot: Apr 21 11:12:37 Info: Dovecot v1.0.beta7 starting up
dovecot: Apr 21 11:12:41 Error: auth(default): shadow(coldmiser,32.32.32.32): Multiple password values not supported
dovecot: Apr 21 11:12:41 Info: pop3-login: Login: user=<coldmiser>, method=PLAIN, rip=32.32.32.32, lip=192.192.192.192
dovecot: Apr 21 11:12:41 Error: POP3(coldmiser): pop3_uidl_format setting is missing from config file
dovecot: Apr 21 11:12:41 Error: child 710 (pop3) returned error 89

(IP addresses have been changed to protect the innocent).

Not much information there so when I try to Telnet to it and feed it raw POP3 commands I get the following:

+OK Dovecot ready.
USER coldmiser
+OK
PASS blahblah
-ERR Authentication failed..

OK, that tells me that I have a problem in my CONF file somewhere, but I can't find it for the life of me.

Here is a copy of my dovecot.conf file.

protocols = imap imaps pop3 pop3s
disable_plaintext_auth = no
log_path = /var/log/mail.log
protocol imap {
}
protocol pop3 {
}
auth default {
mechanisms = plain
passdb passwd {
}
passdb shadow {
}
userdb passwd {
}
user = root
}
plugin {
}

Can anyone see anything wrong in there?

I had the same problem and not sure what caused it to happen.
And the following entry from what I have read is suppose to
be the default. But when I added it, pop3 started working again.
There is a commented out entry in the conf file.

pop3_uidl_format = %08Xu%08Xv

thanks for the tip
 

I also has this problem.

Your advice worked perfectly.

Yep, this worked perfectly for me too. I wonder why they commented it out by default? Oh well, thanks for the solution!

Yes it worked like a charm.

Thank's a lot!
