Dear reader,

Please help me find a way through this problem,

I have CentOS 4.2, dovecot-0.99.11-4.EL4, squirrelmail-1.4.8, While I try to log in as Root (username: root; password: password) I get the error that says,

ERROR: Connection dropped by IMAP server. Query: CAPABILITY

Content of the file /var/log/maillog is as follows

Jun 7 12:56:59 PBX sendmail[5170]: l57Guxxr005170: from=root, size=126838, class=0, nrcpts=1, msgid=< 200706071656.l57Guxxr005170@PBX.COMPANY.COM>, relay=root@localhost Jun 7 12:57:05 PBX sendmail[5171]: l57GuxDv005171: from=< root@PBX.COMPANY.COM>, size=127100, class=0, nrcpts=1, msgid=< 200706071656.l57Guxxr005170@PBX.COMPANY.COM>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1] Jun 7 12:57:05 PBX sendmail[5170]: l57Guxxr005170: to=root, ctladdr=root (0/0), delay=00:00:06, xdelay=00:00:06, mailer=relay, pri=156838, relay=[ 127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (l57GuxDv005171 Message accepted for delivery) Jun 7 12:57:05 PBX sendmail[5172]: l57GuxDv005171: to=admin, ctladdr=< root@PBX.COMPANY.COM> (0/0), delay=00:00:00, xdelay=00:00:00, mailer=local, pri=157317, dsn=2.0.0, stat=Sent Jun 7 22:26:11 PBX dovecot: Killed with signal 15 Jun 11 11:39:00 PBX dovecot: Dovecot starting up Jun 11 11:39:01 PBX sendmail[2704]: alias database /etc/aliases rebuilt by root Jun 11 11:39:01 PBX sendmail[2704]: /etc/aliases: 79 aliases, longest 10 bytes, 811 bytes total Jun 11 11:39:01 PBX sendmail[2709]: starting daemon (8.13.1): SMTP+queueing@01:00:00 Jun 11 11:39:01 PBX sm-msp-queue[2717]: starting daemon (8.13.1): queueing@01:00:00 Jun 11 11:51:27 PBX dovecot: Logins with UID 0 not permitted (user root) Jun 11 11:51:27 PBX imap-login: Internal login failure: root [::ffff: 127.0.0.1]

And I says,

[root@PBX etc]# dovecot -c dovecot.conf Fatal: listen(143) failed: Address already in use

Any help is appreciated in advance,

Cheers,
