Well, this was a single event here (in a period of over 400 days)! But, as I wrote previously, the more serious reason, not to implement my original idea was this: | -- A handfull of my users is sending from email-providers which | freely allow setting of an arbitrary envelope-from. I have to tell these users (above, "a handfull" means 3 users) not to use the webmail interface provided by the foreign providers. On the other hand, we have a functional webmail interface in place, so it should not be too hard, to convince these 3 dissenters ;-) Also, I don't see a need to accept messages targeted to my postmaster@ accounts with an envelope-from [EMAIL PROTECTED] Will I break a RFC-rule with this blocking?
