    Dear friends and coulegues,

    I have an ISPConfig (Installed with the perfect apache server 8.4 tutorial) server with several IP and Domains on it.
    Since the first day of installation i'm having a problem with lots of rejected messages, because of
    Reverse DNS does not match SMTP Banner.
    Whatever i do with Postfix Main.cf and Master.cf, mails are send from the Main(management) IP and domain and not from the IP/Domain sending it...
    Lets say that this are the users:
    localhost = 1.1.1.1 = main1.com (management)
    2nd user = 2.2.2.2 = Domain2.com
    2rd user = 2.2.2.2 = Domain3.com (2nd domain of the same user)
    3rd user = 3.3.3.3 = Domain4.com...
    Here is My Postfix master.cf, please tell me what should i chainge.
    Bellow it, i will post the Main.cf.
    Please let me know if there are other setting that i should change.

    Many thanks for your support and communication

    you did not set -o smtp_bind_address=

    Thank you for the fast answer Florian,
    should i put it on every line with the designated IP? (I thought that because of the beginning of the setting i dont have to in ex: 2.2.2.2:smtp inet n - n - - smtpd -o myhos)
    Should i do it like this?

    2.2.2.2:smtp inet n - n - - smtpd -o myhostname=mail.domain2.com -o smtp_bind_address=2.2.2.2

    Try:
    Code:
    1.1.1.1:smtp inet n - n - - smtpd
      -o myhostname=mail.main1.com
      -o smtpd_bind_address=1.1.1.1

    Thanks Florian,
    But unfortunately it doesn't solve the problem. I entered the whole definition for all domains and IPs, like this:

    2.2.2.2:smtp inet n - n - - smtpd
    -o myhostname=mail.domain2.com
    -o smtp_bind_address=2.2.2.2
    -o syslog_name=postfix-mail.domain2.com
    -o smtp_helo_name=mail.domain2.com
    And still in the mails os at SMTP tests, mail is send from the mangement server and IP: 1.1.1.1 main.com
    I send a mail to [email protected] from [email protected] and got:
    host mx3.hotmail.com[65.55.37.72] said: 550 SC-001 (COL004-MC1F56) Unfortunately, messages from 1.1.1.1 weren't sent.
    Please contact your Internet service provider...


    Maybe i should put also something else in the main/master.cf or ISPc settings?

    Postfix uses roundrobin for the ips. BUt you can define transport-maps so example.com will be sent over 1.1.1.1 and example2.com over 2.2.2.2

    I tried a lot of tutorials but nothing solved.
    Can you please give me an example how should i write the transport and in which file? I tried in:
    /var/lib/mailman/data/transport-mailman
    and entered:
    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    domain1.com smtp:[mail.domain1.com]
    domain2.com smtp:[mail.domain2.com]
    domain3.com smtp:[mail.domain3.com]
    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    and then:
    postmap /var/lib/mailman/data/transport-mailman

    But this forms some kind of loop and mails are not usable...

    you can use /etc/postfix/sender_transports. i.e.
    Code:
    @example1.com smtp1:
    @example2.com smtp2:
    and in master.cf:
    Code:
    smtp1  unix -       -       n       -       -       smtp
       -o smtp_bind_address=1.1.1.1
       -o smtp_helo_name=example1.com
       -o syslog_name=postfix-customer-example1.com
    
    smtp2  unix -       -       n       -       -       smtp
       -o smtp_bind_address=2.2.2.2
       -o smtp_helo_name=example2.com
       -o syslog_name=postfix-customer-example2.com
    Add it to postfix:
    Code:
    postconf -e "sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport"
    postmap the file and reload postfix:
    Code:
    postmap hash:/etc/postfix/sender_transport
    postfix reload
