We have a client that is receiving mail from an organization using a dynamic IP.
How can we allow from this sender? Assuming in helo_access.pcre but what would be the rule for - brmsvexcas02.dyn.corp [10.0.60.14]

Re: Allow from dynamic IP sender?

Here it is: 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

Re: Allow from dynamic IP sender?

Reviving this old thread as I have the same issue - need to receive email from facebook to reset account, but facebook email servers are on dynamic IP address.

Jan  2 21:44:30 omega postfix/smtpd[2192]: NOQUEUE: reject: RCPT from 69-171-232-148.mail-mail.facebook.com[69.171.232.148]: 554 5.7.1 <69-171-232-148.mail-mail.facebook.com>: 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 (69-171-232-148); from=<security@facebookmail.com> to=<xxxx@yyyy.com> proto=ESMTP helo=<69-171-232-148.mail-mail.facebook.com>

How to temporarily adjust the postfix config to receive this email?

Thanks in advance.
