I'm pretty sure that this is not possible.

Hmm... you're probably right about that.  Qmail is probably not
a good choice in that kind of situation.  But then, does one
really have to put up with an ISP which blocks outbound SMTP
traffic?  I wouldn't. :-)

But my point remains: *If* the MTA is Qmail, *then* using VERPs
will not introduce any significant overhead of any kind.

Greetings, Norbert.
