Reverse DNS Problem (with EXIM additional IP)

[musti19]

Hello,
i have configured a additional IP for exim, but i have problems,
that some provider decline my emails with:

SMTP error from remote mail server after RCPT TO:<***EMAIL***>:
host DESTIONATION MAIL SERVER: 550 inconsistent or no DNS PTR record for EXIM IP (see RFC 1912 2.1)

What i do ?

A reverse DNS is already configured for the main + exim IP in datacenter
with same hostname.
notice: I dont use the DNS System of cpanel.

1.
in exim.conf
changed in:

remote_smtp:
  driver = smtp
  interface = EXIM IP
  #interface = ${if exists {/etc/mailips}.....................
  #helo_data = ${if exists {/etc/mailhelo}......................

2. /etc/mailips:
with

*: EXIM IP

3. /etc/mailhelo
with

*: HOSTNAME

4. /etc/mail_reverse_dns

MAINIP: MYHOSTNAME
EXIM IP: MYHOSTNAME

Protected all files, then restart the exim mail server

if i check the IPs on:
Reverse IP Lookup - MxToolbox

no Problem.

if check the IPs on:
Hostkarma Blacklist Removal Form

the main ip have no problem.
The exim IP:
ERROR - Reverse DNS Lookup Failed.
IP [EXIM-IP] does not match [MAIN-IP] - Click here for troubleshoot your Reverse DNS - (Strongly Recommended)

I spend lot of hours without a solution.
Have anyone an idea, where the problem can be?

Hello

Please note that manually editing the Exim configuration file is not required to change the IP address Exim uses to send email. Instead, you can follow the instructions at:

Changing the Sending IP for Outbound Email in Exim

Does the issue continue when following these instructions? If so, you may want to open a support ticket so we can take a closer look at the actual IP address. You can post the ticket number here so we can update this thread with the outcome.

Thank you.
