Just guessing here, but it sounds like one of the following - a) you may have an inadvertent "localhost" in your configuration b) your mail configuration may be seeing host.domain.com instead of domain.com or vice-versa c) your host may have 2 different IP addresses (one internal non-routable 192.168.a.b , 10.0.c.d and one externally visible) this may be causing DNS errors. AFAIK, the error msg is saying that the SMTP server doesn't recognize the hostname you are using to address the host on which the SMTP server resides (or something closely equivalent).

I'm running Zope 2.3.2 (binary release, python 1.5.2, win32-x86) behind IIS on a WindowsNT box.

Does anyone have any experience setting up MailHosts on NT? I keep getting the following error when trying to send email:

Zope Error Zope has encountered an error while publishing this resource. Error Type: SMTPHeloError Error Value: (501, 'Invalid Address')

It looks as though there's some sort of authentication issue between Zope and my SMTP server, which is odd considering they're on the same box. Even when I configure the SMTP server to allow all relaying, Zope can't get through.

Any suggestions will be greatly appreciated.
