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 MAIL From: < m...@sendingserver.com>250 <mailto:m...@sendingserver.com%3e250> 2.1.0 O RCPT To: <b...@localemailaddress.net>554 5.7.1 < 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.
