Troubleshooting e-mail...

[ddrueding]

I've ordred a new domain for a client, and had them set up the DNS. It's pointed to an external hosting site with the MX records pointing to our Exchange server. (looks like this):

schollchyo.com. IN A 38.118.142.221
IN MX 10 mail.schollchyo.com.
www IN A 38.118.142.221
mail IN A 216.228.14.91

I already have 2 other domains set up on the same server from the same ISP so I believe all that is correct. When I try to send a mail from my server, I get the following error (from my server):

david@schollchyo.com on Fri, 18 Feb 2005 17:25:20 -0800
    Could not deliver the message in the time limit specified.  Please retry or contact your administrator.
    <websrv.tweakt.local #4.4.7>

Any suggestions on what to try next would be appreciated.

mx record for schollchyo.com points to mail.schollchyo.com, mail.schollchyo.com resolves to 216.228.14.91, trying to telnet to this IP on port 25 fails.


This indicates that the SMTP server at 216.228.14.91 is down. Is this the correct IP address for the SMTP server?

I shouldn't say it fails.... I just dont get a welcome message.... like the server is down or is somehow firewall protected and blocking me...

This happens almost instantly:

[root@mepis1 root]# telnet 216.228.14.91 25
Trying 216.228.14.91...
Connected to 216.228.14.91.
Escape character is '^]'.
Connection closed by foreign host.
[root@mepis1 root]#

Strange. This is the correct IP, and it is currently hosting mail succesfully for 2 other domains. Thanks for the check, I'll need to look into it more.
