Well, an uptodate greylisting package does not rely just on IP addresses,
but considers 3 parameters: IP address, sender, recipient.

As MJ2 always changes the sender, every new message gets greylisted.
Other mailinglist software always sends from list-owner@......
and works without any problems with our greylisting setup. Not sure
if MJ2 isn't in fact the only package changing the envelope-from for
each message.

Just FYI, I'm a member at several mailinglists at IETF, RIPE and various
international and local projects and I've never seen such problem before.
Yes, of course we can whitelist Alex's server, but this is not what
I consider a proper solution. I'd suggest to look for reasonable
alternatives how to accomplish the same task in MJ2 wihtout changing
the envelope-from header. For example, changing some other header might
resolve this.

	With kind regards,
