Put it this way, I've around 600 valid mailboxes and we're on a leased line hosting our own mail and so far this week alone we've bounced 7500 emails to invalid addresses during the from/to part of the transaction.. cheers, Paul > -----Original Message----- > From: Dickenson, Steven [mailto:[EMAIL PROTECTED] > Sent: 04 February 2004 13:58 > To: Exchange Discussions > Subject: RE: Check recipients at SMTP time > > > Hi Paul, > I also run a Linux SMTP relay (with Exim and > SpamAssassin).
