Exclamation Multiple Domain Name In Outbound SMTP


I recently installed ISPConfig and everything works fine.

However, I am having problem with the outgoing SMTP connections, which is sending emails using multiple domain names, ie. domains hosted on the server, instead of the dedicated name of the server.

As a result of this, the IP address of the server have been added to CBL as a spam server.

I've checked and it seems that whenever Postfix sends emails out, it identifies itself using domains or users hosted on the server and not the actual machine name.

Is there a way to set Postfix to only use 1 specific name, ie FQDN, which is the machine name.

Any help is greatly appreciated.

If you have more then one IP address, you may bind postfix to the main server IP like this:

smtp_bind_address =

Have you set your hostname in main.cf like this:

myhostname = mailserver.mydomain.com

Get ISPConfig support and the ISPConfig 3 manual from ispconfig.org.
