customize auto-response Subject header? [Mailman-Developers]

[James Ralston]

The Subject: header of auto-responses is fixed as:

    Subject: Auto-response for your message to the "%(listname)" mailing list

I'd really like to be able to customize that.  E.g.:

    Subject: thanks for your submission

Or, with variable substitution:

    Subject: thanks for your submission to %(listname)

Or even:

    Subject: Re: %(old_subject_header_contents)

I don't think allow list owners to customize the format of the
Subject: header of auto-replies is unreasonable.  I haven't studied
the code closely yet, but I don't think it would be that complicated,
either.

Thoughts?

Regards,
James
