Nate, can you post the full text of your NDR? Also, have you checked MAPS
or ORBZ to make sure you're not listed there?

Michele,
We have a Checkpoint firewall on our side.
I did try contacting Earthlink and after dealing with them for a while I
felt like I had passed through a gauntlet of "no help". Very frustrating.

what kind of firewall? PIX?
UUNet is known as a spam haven, so it's possible that this server is
blocking all traffic from them. You could always use the telephone to call
the admin of that box & find out.

Subject: IMC problem with Earthlink.net
Scenario:
MS Exchange 5.5. SP4
MS Exchange/Outlook 98 for the clients.
IMC through UU.NET
Here is what I am encountering:
1) IMC functions fine for just about everyone we send to EXCEPT
Earthlink.net
2) Based on the rules we have setup on the firewall the messages for
Earthlink are leaving the firewall destined most often for
mx00.earthlink.net.
3) When we send to earthlink.net addresses we get:
"Unable to deliver the message due to a communications error"
4) Our ISP engineer and they can send email to earthlink from the firewall
as a company.com address so they tell me. However, anyone from inside the
firewall sending to earthlink.com gets kicked back with the above error
code.
5) It seems that something on the earthlink.net side does not like whatever
MS Exchange is doing to the outbound messages. Inbound works fine so far.
Headers reveal that earthlink.net is using:
220 eagle EL_3_4_2 /EL_3_4_1 ESMTP EarthLink SMTP Server
6) I have checked the IMC and found no filters nor any weird configuration
(I haven't changed anything on the setup for the IMC in months and this
whole thing started up about four weeks ago.
7) I haven't found anything in the archives, FAQ, or Technet for the above
error code (at least nothing helpful). I am not seeing anything strange in
the Event logs (not sure if I really would, but checked anyway just to be
sure).
8) Message Tracking doesn't reveal much information as to why the message is
not being delivered.
9) Earthlink.net Tech Support hasn't been much help to date.
Anyone have any ideas as to what could be causing this? My feeling is that
either company.com is being blocked due to spam being sent from us (I
checked UXN Spam Combat and did not find our domain listed, but did find
UU.NET listed). Or, more likely the MS Exchange IMC and earthlink.net are
not talking the same language.
Regards.
Nate Couch
