I don't want to attack - please see the From: address that I use; I often use VERP myself (after 2004-04-08 this address will be invalid and my mail server will reject mail to it). However, whilst it might be possible to enter any From: address in mail sent from MTAs that I install and maintain, it isn't possible at all to send any mail without authenticating with a user name and a password. This user name is then used in the envelope sender dialog with the MTA (EHLO/MAIL FROM:/RCPT TO:/DATA). If the authenticated user then tries to use any other MAIL FROM:, the server won't let him. I'll always know which of my users sent which mail to whom from my servers - this is a recent Postfix smtp AUTH jail. Simply because I won't tolerate forgers or spammers on my patches. --Tonni -- mail: billy - at - billy.demon.nl http://www.billy.demon.nl _______________________________________________ evolution maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/evolution
