    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:

    Code:
    remote_smtp:
      driver = smtp
      interface = EXIM IP
      #interface = ${if exists {/etc/mailips}.....................
      #helo_data = ${if exists {/etc/mailhelo}......................
    2. /etc/mailips:
    with
    Code:
    *: EXIM IP
    3. /etc/mailhelo
    with
    Code:
    *: HOSTNAME
    4. /etc/mail_reverse_dns
    Code:
    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.
