Plesk 12.x / Linux :: Postfix And (Send From Domain IP) Options Are Ignored

My environment: Parallels Plesk v12.0.18_build1200140606.15 os_Debian 7.0 64bits - postfix

In documentation about Server-wide-mail settings

In Plesk for Linux with the Postfix mail server, you can change the IP address used for sending mail. Also, if your server sends mail from domain IP addresses, you can specify which name will be used as a host name in SMTP greetings.

Choose from the three options:

◦Send from domain IP addresses. By default, mail from each domain is sent using the domain's IP address. The host name used in SMTP greeting is defined by the configuration of the mail server.

◦Send from domain IP addresses and use domain names in SMTP greeting. If selected, Plesk changes the mail server configuration so that the SMTP greeting will contain the name of the domain from which an email message is sent.

This option prevent the sender's IP address from being put into public black lists, such as the Spamhaus or OpenBL lists. This might happen if the mail server host name is used in SMTP greeting for the messages sent from domain IP addresses. Some recipient servers consider such messages as spam.

We recommend that you use this option if you host less than 100 domains. In case of a large number of domains, using this option significantly increases the load on the server.

◦Send from the specified IP address. You might want to use certain IPv4 and IPv6 addresses for all outgoing mail.

Sending all mail from the specified address might be useful, for example, if the IP address of the mail server was put into public black lists, such as the Spamhaus or OpenBL lists. If you select None, outgoing mail will not be sent.Click to expand...
