dovecot - Sep 2006 - Dovecot accepts squirrelmail, rejects fetchmail

Hello,

this is a follow-up to the thread "Fetchmail can't talk to
dovecot"
http://www.dovecot.org/list/dovecot/2006-September/016477.html

Increasing the log level I get this in the log filed:

Sep 30 15:04:19 fm dovecot: Dovecot v1.0.rc7 starting up
Sep 30 15:04:22 fm dovecot: auth(default): passwd-file /etc/dovecot_user_file:
Read 1 users
Sep 30 15:05:05 fm dovecot: auth(default): client in: AUTH      1       PLAIN  
service=IMAPsecured
+lip=::ffff:SERVER_IP_HERE rip=::ffff:CLient_IP_HERE       resp=LONG_STRING_HERE
VDBB
Sep 30 15:05:05 fm dovecot: auth(default):
passwd-file(user_name,::ffff:CLIENT_IP_HERE): unknown user
Sep 30 15:05:07 fm dovecot: auth(default): client out: FAIL     1      
user=user_name
Sep 30 15:05:07 fm dovecot: imap-login: Aborted login: user=<user_name>,
method=PLAIN, rip=::ffff:CLIENT_IP_HERE,
+lip=::ffff:SERVER_IP_HERE, TLS

Remember that when the same user name and password come from
Squirrelmail on the same host where dovecot runs, everything works.

Why does it fail with fetchmail? what does that message "unknown user"
exactly mean?

Thank you in advance for any help,

Marco

More exactly: what is in Dovecot configuration that makes it recognize
an user from squirrelmail and call it unknown when it calls through
fetchmail?

TIA,

Fetchmail works fine with dovecot here, and elsewhere, I don't believe
it's a dovecot issue.  If you want to see what's actually happening,
turn on mail/auth debug in dovecot and then login from each of your mail
clients, compare the transactions line by line and see if you can work
out what's wrong.  You're welcome to come back and ask further
questions, but I have to assume this is user error...
