Hi,

I'm having some emails denied by our servers because of problems with the DNS name servers that are sending.

Example:

Header of the denied message:

Received: from nomer-email-1a.nomer.com.br (nomer-email-1a [172.30.30.51]) by nomer-spool-1a.nomer.com.br with SMTP;

Reason: Remote host said: 554 5.7.1 : 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 (pool-)

But, the email sender and SMTP server are legitimate. I already includes the domains in the whitelist but not resolved. I believe that include the IP does not take effect, because denied is in Helo.

How can I do so that I can receive mail from those sources? I'm having trouble with some clients so.

Tks

M Martinatti
