[thelist] Mail server woes.

[Anthony Baratta]

What mail service software are you running. What type of Server is the software hosted on?

It sounds like relaying is not setup correctly on the new server. Normally you would only allow delivery to local accounts from any machine, and deny all remote accounts. Then allow remote account delivery for those users that have authenticated in some way.
