[Mailman-Users] Custom footer based on sender's email

[Rob Jackson]

Ok, never mind on the problem with re, I don't know why I couldln't figure
that out before, I just didn't look hard enough.  Although it still doesn't
work.  Here is what I have now.

I was aware of the

if not header and not footer:
        return

And made sure that wasn't a problem.  But it seems I was probably exiting
out someplace else.  I used to be getting an error when I had it other
places, and then when I moved it to the end, the error went away, well it is
back now that I am actualy hitting the code before it exits.  Here is my
error.  Thanks for helping out with my ignorance.

"May 11 11:54:49 2006 (11951) Uncaught runner exception: global name 're' is
not defined"

What is the best way to define 're'  I have tried looking at other examples
throught the program and have been unable to determine how I need to do
this.

Thanks
-Rob

Elvis has left the building...

I.e. putting the code there will only get those messages in which the
mailman header/footer has been added as a separate mime part to a message
not already multipart/mixed.

Starting from the top of Decorate.process() we have several exits:

    # Escape hatch if both the footer and header are empty
    if not header and not footer:
        return

If there is no defined msg_header or msg_footer, we leave.


    # If we couldn't add the header or footer in a less intrusive way, we
can
    # at least do it by MIME encapsulation.  We want to keep as much of the
    # outer chrome as possible.
    if not wrap:
        return

If we have managed to add the header and/or footer to a text/plain message,
or if the message was already multipart/mixed and we added the header and/or
footer as separate mime parts, we are done and leave here.

The only thing that gets beyond here is the case where we create a new
multipart/mixed 'wrapper' with header and/or footer parts and the original
message as a message/rfc822 part.

You first have to see whether or not you have msg_header and or msg_footer
for the list, and also what the structure of the incoming message is. In the
simplest case of a single part text/plain message, you could add the three
lines just prior to

    # Escape hatch if both the footer and header are empty
    if not header and not footer:
        return
