[Discuss] E-mail Server Help?

[gmongardi at napc.com (Grant Mongardi)]

It may be that you don't have an actual MX record and that prodigy.net
doesn't offer a wildcard. If that machine doesn't have an MX record than
most mail servers will reject any mail sent from. The idea is that they
don't want to be forwarding mail for a machine that could just be
temporarily on a provider's network (to prevent spammers). You'll need to
ask prodigy.net to add an MX record for your IP address.
