I'm not sure if this is a procmail issue or not. About a year ago, we had
return-receipts working here at the college for messages sent to any of
our users. Shortly after installing procmail as the default mail server,
I noticed that return recipts not longer worked. I hadn't thought much
about at the time, but now our users are requesting it and I do not know
how to solve. Does anyone know how return-receipt is activited? I know
that the system will look for header return-receipt, but not sure how to
set it up globally.
Is this is procmail or sendmail (Berkeley 8.9) issue?
It's a sendmail issue, not a procmail issue. Sendmail 8 does not by
default support Return-Receipt-To:, mainly because it was a horrible,
broken, dangerous, and just plain bad idea to start with. Use DSNs
(Delivery Status Notifications) instead. What are your users actually
requesting? RRT will not be very useful for off-site communications,
as I would say that most sites don't support it any more, and unless
you have a very complicated mail configuration, an RRT will either come
back immeadiately or you would get a bounce message, no?
Let the broken thing die.
