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?
