After thinking that there was something wrong with one of my credit card
companies' mail server, I noticed the following in my maillog:
Feb 12 09:17:37 mail courierd: newmsg,id=00164819.45D0A131.00001C49: dns;
localhost (localhost [127.0.0.1])
Feb 12 09:17:37 mail courierd:
started,id=00164819.45D0A131.00001C49,from=<>,module=esmtp,host=alerts.chase.com,addr=<Cha...@alerts.chase.com>

Backscatter bounce dropped.
Feb 12 09:17:37 mail courieresmtp:

Feb 12 09:17:37 mail courieresmtp:
id=00164819.45D0A131.00001C49,from=<>,addr=<Cha...@alerts.chase.com>,status:
success
Feb 12 09:17:37 mail courierd: completed,id=00164819.45D0A131.00001C49
For now, I've set BOFHSUPPRESSBACKSCATTER=none in bofh to see if I can
get a copy of the actual message (is there anything else I can do, or
maybe a way to whitelist this specific address so I don't have to
completely disable backscatter suppression?).
I just wanted to see if anyone else has run into this or a similar
issue. The timing of these messages corresponds directly with
non-bounce messages (specifically, the "your bill is due in X days" or
"we have mailed out your statement" type emails), so I'm concerned that
there might be a glitch in courier's backscatter detection (or chase.com
is screwing something up in their message headers).
I'm currently a little outdated on courier (.53.2) but am compiling
.54.2 now, in case that will help, too.
