Is this the same system on which you installed the patch described in
http://www.rhyolite.com/pipermail/dcc/2004/002280.html  ?
If so, the purpose of that patch was to figure out something to
say to sendmail at the end oa message has been rejected by at least
one receipient but there is no specific reason to give sendmail.

When I made the patch, I had a theory how that might reasonably
happen, but I can no longer see it.

Could you send me (not the mailing list) the /var/dcc/log file
for one of these failures with the patch installed?

Do you still have the core file and matching /var/dcc/libexec/dccm from
before you installed the patch?  If so and they are not too large,
I might be able to figure out something from them.
