Send root mail to external domain SMTP connection fails Plesk 11.5.30 (Linux/CentOS)

[bskrakes]

Hello,

I have a Plesk Server which receives the following error when try to send root system emails to an external domain:

Dec 22 03:31:32 ip-XX qmail: 1387708292.589568 starting delivery 969: msg 297478 to remote user@domain.com
Dec 22 03:31:32 ip-XX qmail: 1387708292.589609 status: local 0/10 remote 1/20

Dec 22 03:31:33 ip-XX qmail: 1387708293.085104 status: local 0/10 remote 0/20

Dec 22 03:34:27 ip-XX courier-imapd: LOGOUT, ip=[::ffff:127.0.0.1], rcvd=12, sent=365

All of my domains can send and receive emails no problem however the root emails stay stuck in queue. I can deliver the root emails to a local address which to me suggests that the issue is possibly a routing, DNS, SMTP or relay problem.

I've tried several suggestions via the web:

• http://xf.wiki.mithi.com/index.php/Server_is_unable_to_establish_an_SMTP_connection
• http://kb.parallels.com/en/1398
• http://www.linuxweblog.com/blogs/sandip/20081230/plesk-root-email-delivery
• http://www.hosting.com/support/plesk/check-the-mail-log-on-plesk-server/

Any suggestions would be greatly appreciated.

Thank you,

Well I built a new cloud server with basic Plesk install and was able to successfully send root system messages to an external domain. This makes me think that QMAIL is broken...

Also I am unable to receive emails at HOTMAIL, GMAIL, etc. from the root account. There is no error when sending to email providers like HOTMAIL or GMAIL:

Dec 23 10:39:49 ip-XX /var/qmail/bin/relaylock[22428]: /var/qmail/bin/relaylock: mail from 2.232.3.52:53761 (2-232-3-52.ip210.fastwebnet.it)

NOTHING AFTER THIS LINE IN THE LOG, MOVES ONTO NEXT MESSAGE

I've even tried repairing the mail server:
