Hi Zhang,
I have a client which might not have DNS set up correctly
and i see on the mail log
Oct 22 04:01:07 ct-openldap postfix/smtpd[7478]: NOQUEUE: reject: RCPT from unknown[175.45.36.69]: 450 4.7.1 CDSSRVDCEX01.hkdc.cds-net.com: Helo command rejected: Host not found; from=kivenwang@cdsshanghai.com.cn to=carl.shen@OURDOMAIN.comproto=ESMTP helo=CDSSRVDCEX01.hkdc.cds-net.com
We could not received their mail as it being reject by our mail server
they ask us the put them on the whitelist with its IP, they said this way our mail server will check the domain and its IP, but i could only seen the domain to be added in whitelist, there is no place to add ip.
We temporary disable the reject_unknown_helo_hostname by removing it in main.cf
# HELO restriction
smtpd_helo_required = yes
smtpd_helo_restrictions =
permit_mynetworks
permit_sasl_authenticated
check_helo_access pcre:/etc/postfix/helo_access.pcre
reject_non_fqdn_helo_hostname
reject_unknown_helo_hostname <---by removing this
but i know if there is a place to whitelist its domain corresponding to the IP, like we are creating there DNS record. it could solved the problem. we are using the iredadmin -PRO
Thanks
