I'm not very experienced but tried telnet a few times, and am not that far i
can reproduce that (without some detailed hints).
What i could do was send debug messages to my debug window and so i could
follow a bit of the conversations. As locally everything goes fine, nothing
Quote:> Is the ISP hosting an open relay?
I'm afright i don't know what that means...
Quote:> Are you tracking error messages from the ISP's mailserver?
I wouldn't know how to do that.

I have 4 mailboxes to test upon, with different providers. When doing the
test locally they all arive. With the Cgi on the webserver, only my mailbox
on planet.nl arives.

Stupid, i haven't thought of that. I'll do that straight away.
