[Mimedefang] Access to email Headers in mimedefang-filter?

[Mark Wiater]

Hello,

I have a requirement to respond to email under certain circumstances.

Specifically, if the intended recipient is X, I need to discard the email and
send a canned message back to the original sender with canned text directing
them to use another process to achieve their goals.

I was thinking that I could use a simple

send_mail,
action_discard

process but am running into difficulty in some instances. I have found a few
instances where the $Sender variable does not represent a valid email
address. After discovering that, I thought it might be wise to use the same
technology that mail clients use in replying to a sent message.

If I'm not mistaken, replied-to email should be sent to the address in the
Reply-To: or From: header information, respectively. (If this is wrong, I'd
love to hear the right way.)

If the above is correct, how can I get that data, within the confines of
mimedefang-filter? David, have you ever thought about a %Headers hash (there 
have been other times that I would have liked to know what was in the 
headers)?

Thanks for your help,

Mark
