It's not a milter per se. It is a Postfix policy service
. The interface is
different from a milter. I don't know if there is anything comparable in
sendmail.

Yes, it could.

Yes, I suspect it is Postfix specific.

ACK

See my reply to Jim if you have opinions on how / when it's done.


See 


Intriguing.

My python is quite bad, but that looks like it reads from STDIN and 
writes to STDOUT.  Which I think is not directly compatible with milters.


But, it would serve as a starting place for a milter.

Sadly I don't think that will work as is for me.  I'm running Sendmail 
and would need a milter.

Thank you for the links Mark.

It looks like mine is based off of the original (or a close variant 
there of).


The version I'm running:

   $VERSION = '$Id: mm-handler,v 1.2 2002/04/05 19:41:09 bwarsaw Exp $';

mm-handler-5100:

   $VERSION = '$Id: mm-handler 5100 2002-04-05 19:41:09Z bwarsaw $';

It looks like the changes consisted of the following:

 - Changing how the sendmail binary is called ($SENDMAIL) to pass 
different options:

- Change the ErrorMode from m (mail back) to q (return code)
- Change the from to be the null reverse path.
- Set to never return a DSN.
- Sets outgoing DNS parameter to only return headers.
- Sets an outgoing envelope ID.
 - I extensively re-wrote / re-factored what was a simple multi-line 
print to use MIME:: modules to build a proper DNS with all three 
sections.  (The last section is just the headers b/c of the outgoing 
SMTP parameter.)
 - I tweaked the ADDR: label to return an SMTP error (553 5.1.1 
<$list\@$server>...) error message.


Let me know if you'd like me to port these changes to mm-handler-2.1.10.

I may do this anyway to be running a newer mm-handler*.

Aside:  I've often contemplated a milter that could hook into the Python 
pickles to optionally reject messages at SMTP time if a non-subscriber 
tries to send an email to a list.

What is the authoritative version / source of mm-handler?

I've got three different versions:

 - 2.1.10
 - 5100
 - modified form of an unknown version

I made some changes years ago to have mm-handler return a properly 
formatted DSN.  But I don't know what version it was based on.  As such, 
I can't submit patches.


I'd be willing to make similar changes to current and submit them if 
you're interested.


In hindsight I'd like to also add the Auto-Submitted: auto-generated 
header to the DSN.  And make sure it uses the Null Reverse Path.

Please make whatever changes you feel are needed and post them here, and
I will include them in the next release.
