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

Aha.. replying to my own message.

There is, in fact, a kind of solution. Stuff found on the sendmail.org
website at:

http://www.sendmail.org/~ca/email/dsn885.html

In a nutshell, you have to compile sendmail with the _FFR_DSN_RRT_OPTION
which enables recognition of the Return-Receipt-To: header in 8.8.5 or
later. You can then use the Option RrtImpliesDsn=True to make sendmail
respond to the presence of the Return-Receipt-To: header as if it was a
DSN request.

Setting the option to false means it still recognises the
Return-Receipt-To: header, but does nothing with it and strips it from the
header.

One important note: This feature is undocumented and FFR means For Future
Release. Basically, this feature might be removed in future versions of
sendmail without any written notice.
