How do I change the outgoing mail server?

[Crys]

Hello there,

I was wondering, how do I change the outgoing mail server on vBulletin? I would like vBulletin to use a separate server for just the emails going out instead of the server the forum is on (subscription emails, activation emails, etc...).

It's an unusual request but it'll really make a huge difference for me if I could manage to do this.

Much appreciated

Ok,

I think I figured out how to change the mail server however, I'm now getting returned emails because of this error:

This message has been rejected because it has
an overlength date field which can be used
to subvert Microsoft mail programs
The following URL has further information

Is there a way to change the overlength date field so this doesn't happen in the future?

Thanks ^_^
