Subject: helo being rejected
Hello All,
I have a clients who's email server is getting a lot of helo
rejects from it (windows box). The client has a .NET domain for their
servers ( hardware ) and a .COM for their email address.
I manually had a conversation with my postfix server that has
these settings:
reject_invalid_helo_hostname,
check_helo_access hash:/etc/postfix/helo_access,
reject_invalid_helo_hostname,
reject_non_fqdn_helo_hostname,
I verified reverse DNS, all domains exist etc.
Here are my results:
220 receivingserver.net ESMTP Postfix
EHLO sendingserver.net 250-receivingserver.net
250-PIPELINING
250-SIZE 24000000
250-ETRN
250-AUTH DIGEST-MD5 PLAIN LOGIN CRAM-MD5
250-AUTH=DIGEST-MD5 PLAIN LOGIN CRAM-MD5
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

sendingserver.net>: Helo command rejected: Helo Chec
Any ideas appreciated!
Thanks!
=====================
That error message is not coming from the *_helo_hostname checks, it
must be coming from your helo_access map. Show the transaction logging
from the maillog and the contents of your helo_access.
