Problem with sending mail from a domain with Google MXs

Question

Exim

Greetings,

there is a domain (domain.com) attached to the Dedik, on which the EXIM server is installed.
MX records on the domain point to Google.

# host domain.com
domain.com has address ip.ip.ip.ip
domain.com mail is handled by 1 ASPMX.L.GOOGLE.COM.
domain.com mail is handled by 5 ALT1.ASPMX.L.GOOGLE.COM.
domain.com mail is handled by 5 ALT2.ASPMX.L.GOOGLE.COM.

You need to send mail from the dedicator. But there is a problem - it does not come to some addresses (on different hosts).
It returns like this:

SMTP error from remote mail server after RCPT TO:<[email protected]>:
host cluster.relay.agava.net [89.108.67.8]: 550-Your Message rejected.
550-Please use your internet provider SMTP Server.
550 REASON: Bad PTR."

Several domains are linked to the dedicator, so this scheme needs to work for everyone.

How to overcome it?

Thank you.

Answer 1

The PTR does not have to match the domain that the mailer serves. It just needs to be present and, if possible, not be something like "pppoe-35.86.32.217.domain.ru".

Answer 2

Specify normal ptr records or use someone's normal smtp?

Answer 3

Write a PTR record for the domain.
