Adding a "telltale" to the "Subject:" line

[Pete Holsberg <pjh @ mccc . edu>]

I looked at the FAQ but didn't see the answer to this.

Is it possible for majordomo to add a short phrase to the
beginning of the subject line of an original message?

I have users who would like to know which messages come
from our majordomo-managed mailing list.

Thanks,
Pete
