    Alright I have been trying to configure a server to send email for 3 months now and can't get this stupid crap to work consistently. I purchased cPanel thinking that this program could configure it easier then what I was using... But besides the point...

    I have 3 personal domains setup in a shared IP enviroment.

    Domain1 was setup as principal primary domain. Server name is "mail". DNS record exists for "". PTR record with ISP is set to "". System passes all tests on

    From there I added and in cPanel. I pointed MX records for these to "". System is able to send/receive mail from these domains. System can email of the harder servers I configured for) from all domains.

    I having trouble emailing from and These messages get hung up in the queue. Is this standard in a shared hosting enviroment what is set wrong? I can't take it anymore please help. I'm thinking it is some kind of DNS related issue. But I have no clue... Here is a sample queue failure:
      cwd=/usr/local/cpanel/whostmgr/docroot 4 args: /usr/sbin/exim -v -M 1SRTO2-0000sk-VO
