That suggests that sendmail is telling dccm that the message is spam
as far as sendmail is concerned and that the default "option MTA-last"
is in effect so that sendmail overrides the dccm whiteclnt file.

It should not necessary to whitelist the SMTP envelope Mail_From
domain name in both the sendmail access database and the dccm whiteclnt file.
To whitelist using the sendmail access db, you need to modify sendmail.mc/cf
with `/usr/var/dcc/libexec/hackmc -O` or equivalent
and use a line like this without "DCC:"
host.domain.com OK
The current result of hackmc has "host DCC:message", "host DCC:reject message"
and so forth all meaning "sendmail hates host and should tell dccm"
In general, see the comments in hackmc.
If changing the /etc/mail/access (or wherever) file does not fix the
problem, these questions might give clues:
- has sendmail.cf/mc been adjusted with hackmc or an equivalent?
If so, with which hackmc args?
- does /var/dcc/whiteclnt or relevant per-user
/etc/mail/userdirs/local/$USER/whiteclnt files contain
"option MTA-first" or "option MTA-last" ?
(see the main dcc man page concerning those)
- what do the /var/dcc/log files for the mail messages say?
I'll change the sendmail.cf rules added by hackmc in the next release
so that "host DCC:OK" is parsed as "host is OK for both sendmail & DCC"
instead of the current "host is bad and the error message to give dccm is OK"
