Just a follow-up.

With the help of Tonino on the chkuser list, I was able to determine 
that these messages (some messages?) were being rejected due to SPF 
failure. The messages were being automatically forwarded from the old 
domain (as a temporary measure), which caused the failure. There was no 
indication in the logs that the messages were being rejected.

The qmailtoaster.com package contains the qmail-spf.rc5 patch 
(http://www.saout.de) for SPF processing. I looked at the code and it 
doesn't appear to do any logging. I wrote to the author about it, and 
haven't heard back (yet). I may have to patch-the-patch to get logging 
of SPF rejections.

Any qmail-ers out there have a patch for SPF that logs its activity?
TIA
