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.
