[SLE] Postfix RCPT from unknown - Why?
  • From: "David Rankin" <drankin@xxxxxxxxxxxxxxxx>

After adding:

smtpd_client_restrictions = check_client_access
cidr:/etc/postfix/client_check.cidr, reject_rbl_client relays.ordb.org,
reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client list.dsbl.org,
reject_unknown_client

I can't send mail from Postfix at home to postfix at work. The problem
is the "reject_unknown_client" restriction which causes the server at work
to reject the message. If I remove the restriction it works fine. The error
is:

Jul 26 23:14:10 bonza postfix/smtpd[22176]: connect from
unknown[66.76.63.120]
Jul 26 23:14:10 bonza postfix/smtpd[22176]: NOQUEUE: reject: RCPT from
unknown[66.76.63.120]: 550 Client host rejected: cannot find your hostname,
[66.76.63.120]; from=<david@####skyline.com> to=<david@######lawfirm.com>
proto=ESMTP helo=<nemesis.3111skyline.com>
Jul 26 23:14:11 bonza postfix/smtpd[22176]: disconnect from
unknown[66.76.63.120]

(Note -- I inserted the #### stuff in this message to prevent the address
from being skimmed from list archives)

What I don't understand is why I get the log entry of "RCPT from
unknown[66.76.63.120]"? 66.76.63.120 is certainly known. It's
3111skyline.com. Why is the "unknown" happening. Any ideas??? Is it a
problem with my home mail setup not sending a hostname?? (not likely, helo
got it) is it a domain mx record problem? Is it a timeout problem on the
reverse lookup?

Any help will be appreciated...
