Hi there,

Sorry to be so long replying - I've been busy with work & haven't
been reading the list. In case you're still having problems - and for
the benefit of teh Googles - it looks to me like mail.ipr.edu may be
doing clever greylisting & stuff.

If I telnet in and - giving a legitimate from: address - try sending
a message to jason@(protected)
try sending one to root@(protected),
I think there is no MX record for abulafia.ipr.edu).

I don't know for sure whether things have changed at mail.ipr.edu in
the last week, but maybe it's rejecting the mail because the from:
address is invalid. I would try changing the from: address set by
Joomba.

Stroller.
