Hm - this appears to be limited in effect.

If I understand this correctly, it is laundering incoming messages that
are being moved via the mailsource to the final location; however, my
system presorts messages with maildrop and .forward+... files, thus the
"ignoring of broken references" needs to be done when the Group buffer
is assembled and not as incoming messages are sorted.

BTW, is the regexp (...broken-references-mailers) case sensitive?
Pegasus uses "X-mailer: Pegasus ..." with lower-case m (but testing with
upper-case M in an existing IMAP folder doesn't help either).
