Server component Postfix

From Kolab wiki

Function

Postfix is the central mail transfer agent (MTA) of the Kolab server.

Patches

Kolab currently uses two patches for the postfix server. All have now been integrated and if you use the newest postfix versions you won't need to install a patched postfix server.

Feature: configurable MAILER-DAEMON replacement for the
null sender address that is used by the pipe(8) delivery
agent on the command line and in message headers. Command-line
address quoting is disabled when the replacement is empty.
File: pipe/pipe.c.

Configuration

There exist seven templates for the postfix configuration:

• ldapdistlist.cf
• ldaptransport.cf
• ldapvirtual.cf
• main.cf
• master.cf
• transport
• virtual

Please note that the OpenPKG Kolab version still uses an older, patched postfix version and you will need to fix the configuration according to the version you are using.
