Yes, it does. It doesn't change the message headers, but it does change the SMTP MAIL FROM: to be the user for whom the original delivery to procmail was made. Apparently the way they have sendmail configured, this did not happen when a .forward file was used. The solution is to obtain the original envelope sender (possibly by extracting it from the Return-Path header, but it may be available as $1 or $2 depending on how procmail is invoked from sendmail) and pass it back to sendmail again with the -f option, which can usually be accomplished like so: :0 * conditions ! -f "$ENVELOPE_FROM" forward <at> address.dom (assuming $ENVELOPE_FROM contains the address extracted from Return-Path or wherever). This probably won't work if the MTA command-line interface is not sendmail-compatible, so use with appropriate care.
