dovecot - Jul 2009 - Several errors

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:

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

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

It means you're using some weird mix of both. Get rid of all of Dovecot
v1.0 binaries (rpm -e dovecot or something) and your problems should go
away.

After a
chown root:root /var/mail/vhosts/mydomain.tld/user
chmod 700 /var/mail/vhosts/mydomain.tld/user

I get the following error in my log:

Jul 25 13:32:19 dovecot: Fatal: chdir(/var/mail/vhosts/mydomain.tld/user)
failed: Permission denied (euid=0(root) egid=1000 UNIX perms seem ok, ACL

When and where did I spoke about FREE? I never said I didn't want to pay
for it!!! Please don't think for me...

Attitudes? Since when is a normal business inquiry not appropriate?

Sorry, but the answers on this mail group are written with as few words as
possible - if it was written in Finnish, I'd understand just as much as I
do now.
Googling on a Dovecot problems results always in www.dovecot.org or one of
its child sites. Always.
Googling on a Linux question results always in experts-exchange. Always.

I don't agree. I know the way of asking isn't the most nice way - and I
also apologise to them, who assisted me! But who cares if I agree with
someone, who didn't assist me at all, but who only is capable of writing
negatively about me?

Pretty bad? You misunderstood me, my friend. Try to read reasonable next
time. That helps!
