[ProgSoc] sendmail & DSN/Return-Receipt-To:

[daedalus <daedalus@nospam.snafu.tech.its.maynick.com.au>]

Calling sendmail gurus,
	On moving to Solaris 2.6 and thus a new version of sendmail
(8.8.5 -> 8.9.2) masquerading of the Return-Receipt-To: header is broken.
Previously all addresses outbound were masqueraded by using a btree
database to match the actual address to the official address so that
external ppl would only see the official address.

Now, however, the Return-Receipt-To: header is making it through without
getting masqueraded, while the From: header gets changed as per usual.

Anyone have ideas as to why this would change? Is it worth trawling
through the config file (as I have been) trying to work out why it broke,
or should I just recompile sendmail with a checkcompat() routine to strip
out all Return-Receipt-To: headers? Or can I use a Scheck_compat ruleset
to do the same thing?

The bat book is kinda helpful, but since it doesn't have a recipe for
exactly what I want to do, it's kinda difficult to work this out. That and
my sendmail is a bit rusty. :)
