Hi All,
I have the problem with receiving the mails, when I go through SMTP logs
I found maximum error " DENIED_RDNS_MISSING and DENIED_OTHER "
If I put the domain in adjust whitelist senders, then it solved, but
there are lots of domain that I can't put it manually or monitor daily.
Please give me the best solution so that I can fixed that issue.

DENIED_RDNS_MISSING: These are most likely spam. I would be very leery
of whitelisting any domain related to this error, and whitelist only as
a temporary measure. If a user identifies the domain as legitimate,
notify the mail administrator of the sending domain of the problem. The
sender's emails are being rejected by many destinations, including
gmail, etc.
DENIED_OTHER: These are rejections most likely due to scanning, which
would be either an email containing a virus, or one which scored very
high by spamassassin. I would not whitelist these either.
Bottom Line, your QMT is working effectively. Don't muck with it. It's
likely that over 80% of the messages which hit your server will be
rejected by spamdyke. This is normal (and a good thing!).
