[Dovecot] Several errors

Sat Jul 25 01:07:56 EEST 2009

Hi,

Running OS: CentOS 5.3 (2.6.18-128.2.1.el5)

1.
My Linux distribution comes with Dovecot 1.0.7. After trying to make it
running, I encoutnered many problems. So I decided to upgrade to 1.2.1.
When running dovecot -r from CLI, it returns with version 1.2.1.
But at the top of the log file it says: Info: Dovecot v1.0.7 starting up

So I am not sure which version I am running.

That's the first problem.

The other two problems I am having were also actual before updating to 1.2.1:

2.  Every minute, the following lines (except for the timestamps, which
are different, ofcourse) are being added to my log file:
dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing
dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing
dovecot: Jul 24 23:54:24 Error: child 3712 (login) returned error 89
dovecot: Jul 24 23:54:24 Error: child 3713 (login) returned error 89
dovecot: Jul 24 23:54:24 Error: imap-login: USER environment missing
dovecot: Jul 24 23:54:24 Error: child 3714 (login) returned error 89

3.  As soon as a user tries to log on via POP3 (telnet localhost pop3),
the user is kicked out.
The log file says (username and domain name are fake):
dovecot: Jul 25 00:01:02 Info: pop3-login: Login:
user=<user at mydomain.tld>, method=PLAIN, rip=::ffff:127.0.0.1,
lip=::ffff:127.0.0.1, secured
dovecot: Jul 25 00:01:02 Error: POP3(user at mydomain.tld):

dovecot: Jul 25 00:01:02 Error: POP3(user at mydomain.tld):

dovecot: Jul 25 00:01:02 Error: POP3(user at mydomain.tld): Couldn't init

dovecot: Jul 25 00:01:02 Info: POP3(user at mydomain.tld): Mailbox init
failed top=0/0, retr=0/0, del=0/0, size=0

And the user gets:

[root at nestorix ~]# telnet localhost pop3
Trying 127.0.0.1...

Escape character is '^]'.
+OK Dovecot ready.

I have no clue at all, where I should start solving the problems. Somebody?
