That IP addreses is not an IMail server and it does not recognise that user
name. Here is the Telnet session I tried:
220 grey.mydomain.com ESMTP Postfix
vrfy root
252 <root>
ehlo
250-grey.mydomain.com
250-PIPELINING
250-SIZE 10240000
250-ETRN
250 8BITMIME
ehlo mydomain.com
250-grey.mydomain.com
250-PIPELINING
250-SIZE 10240000
250-ETRN
250 8BITMIME
mail from: [EMAIL PROTECTED]
250 Ok
rcpt to: [EMAIL PROTECTED]
550 <[EMAIL PROTECTED]>: User unknown
The orginal sender also included a 'Delivery Status Notification' and that
is what is being returned. That server, if using the IP it shows, is not
connecting to your IMail server (unless this is via a firewall).
I'm trying your server again and am having troubles connecting, so I cannot
verify it the user and domain are on your IMail server.
Maybe this other server (the IP address) is in the secondary or other MX
path in that domains DNS records?
Here is what I get for digitalcollision.com and I don't see your mail server
in any of the MX records, do you?
digitalcollision.com.
nameserver = NS1.MYDOMAIN.COM.
nameserver = NS2.MYDOMAIN.COM.
nameserver = NS3.MYDOMAIN.COM.
nameserver = NS4.MYDOMAIN.COM.
212.69.201.110
10, a.mx.mydomain.com.
10, b.mx.mydomain.com.
10, c.mx.mydomain.com.
Unless your IMail server is a, b, c.mx.mydomain.com, I cannot see how any
mail for digitalcollision.com gets to your IMail system.
If you can telnet in and verify the user in IMail, then there is definitely
a different host or route to it, that is responding when I connect (and the
sending mail server). Now I have to say the problem is very likely to be
DNS!! You can resolve the name locally (maybe with your DNS), but others
using the Authorative servers, get different data, so connect to different
host.
