Hi everyone,

I am trying to send an email to a friend of mine who has comcast as their email and I have yahoo. I get the following message when attempting to send an email:Reporting-MTA: dns;web1-a.imodules.com
Received-From-MTA: dns;web1.planetalumni.net
Arrival-Date: Tue, 3 Oct 2006 13:20:32 -0500

Final-Recipient: rfc822;[email protected]
Action: failed
Status: 5.0.0
Diagnostic-Code: smtp;521-EHLO/HELO from sender does
not map to web1-a.imodules.com in DNS
521-sending machine name must be provided as a fully
521-qualified domain via EHLO/HELO command.
521-see section and 4.1.4 of RFC 2821
521 521: Comcast requires that all mail servers must have a PTR record
with a valid Reverse DNS entry. Currently your mailserver does not fill
that requirement. For more information, refer to:

I then clicked on the link for more info and it talked about configuring ptr records and rdns, which I have no idea how to do. Can anyone help me figure this out?

This is a Yahoo issue, there is nothing wrong with your computer. Forward the message to Yahoo technical support as there's nothing you can actually do about it, unless you want a crash-course in how email works :whistling:
