Apr 17 13:44:43 mail postfix/smtpd: NOQUEUE: reject: RCPT from revws10-22.214.171.124.intermedia.net.ar[126.96.36.199]: 554 5.7.1 <revws10-188.8.131.52.intermedia.net.ar>: Helo command rejected: ACCESS DENIED. Your email was rejected because the sending mail server appears to be on a dynamic IP address that should not be doing direct mail delivery (10-192.99.240); from=<email@example.com> to=<firstname.lastname@example.org> proto=ESMTP helo=<revws10-184.108.40.206.intermedia.net.ar>
Added to /etc/postfix/helo_access.pcre/ but seems not work:
# Prepend HELO hostname of sender server
What should I do now?
Did I add something wrong?
I want to whitelist this domain name or user's email address to let his emails successfully come into our inbox.
Please help, thank you very much!
