Thanks for working with me..
I already have the MX records setup and have been recieving and sending mail on this server. I have found in the Deferred mail que that I have a bunch of messages backed up that either have "connection timed out" or "connection refused" as the reason why they are deferred. Now, when I investigated the connection refused issue, most of the messages that were refused were going to sbcglobal.net e-mail addresses. Here is the actual error message when I check the deferred que:
Sender:ccottingham@sitediscovery.com
From Host: localhost.localdomain
From Domain: sitediscovery.com
From IP:127.0.0.1
Reciepients:douglassw@sbcglobal.net
To Domain:sbcglobal.net
Content Filter:undefined
Size:3299243
Reason: Connect to sbcglobal.net[75.31.55.210]:connection refused.
Ok.. sbcglobal.net is not at 75.31.55.210. That is my external IP.
When I try to ping sbcglobal.net from the terminal, it gives me this:
[root@zcs ~]# ping sbcglobal.net
PING sbcglobal.net.sitediscovery.com (75.31.55.210) 56(84) bytes of data.
64 bytes from adsl-75-31-55-210.dsl.scrm01.sbcglobal.net (75.31.55.210): icmp_seq=0 ttl=64 time=0.238 ms
64 bytes from adsl-75-31-55-210.dsl.scrm01.sbcglobal.net (75.31.55.210): icmp_seq=1 ttl=64 time=0.196 ms
So, it looks like that the zcs server is taking it upon itself to append sitediscovery.com to any address that it cannot resolve. I tried this with a bogus address that does not exist and I get the same result. The zcs server appended sitediscovery.com to the name instead of reporting it as an unknown host.
Hopefully this is a bit more clear on the issue I am having. In a nutshell, I cannot send mail to any host @sbcglobal.net. I am also having issues sending mail to anyone.. I keep getting intermittant connection timed out issues. The mail just sits in the deferred que. If I requeue it, it just comes right back to the deferred que with the reason listed as either "connection timed out" or 'connection refused" .. Its driving me quite mad!!
Thanks again..  |
