From what I can determine, userMailer defaults $reply to as false
line 78 in userMailer.php: function userMailer( $to, $from, $subject, $body,
and nothing in the 1.6.7 ever calls it setting a reply-to address. In
particular, it doesn't seem to be set by User::sendmail().
I suspect that this is why some recipients are not receiving password resets
from my wiki; their spam blockers may reject mail without a reply-to. I'm not
sure Fixing this may require also committing a fix for bug 4347.
Very few mails have a reply-to set.
