Hi,
Our two outbound mail gateways have been blacklisted by
Comcast, and
the normal form (http://www.c
omcastsupport.com/Forms/NET/
blockedprovider.asp) is returning a weird error. See
below.
Your request for IP block removal has been denied for the
following
reason:
- You have been blocked from emailing the Comcast network
because
we have determined that you are sending email from a
dynamic/residential IP within the Comcast domain. Comcast
does not
allow subscribers to send email from a mail server other
than
smtp.comcast.net. All mail should be sent through Comcast's
mail
server. For information on configuring your machine to use
smtp.comcast.net, please follow the link below.

Now, I'm pretty sure that our IP address block (147.9) is
not part of
Comcast, and we've been unable to get a hold of a person
that can
help explain this. Any help would be most appreciated.
Thanks,
