[rt-users] Sendmail - outgoing mail

[tmaciak at ci.grand-rapids.mi.us]

Anybody know of a way to disable sendmail for all mail that is not within our specified "domains" ?
i.e. - we process tickets to webmaster from yahoo, hotmail blah blah blah and it tries to autoreply
To them with the ticket creation.  Obviously we still want to send the mail internally for our own users.

Any information on how I could od this would be very helpful! 

Thanks,
