How to config postfix in Zimbra

Question

I am developing a content filtering app for zimbra. I have a problem with the config postfix MTA.

In main.cf

 content-filter:smpt-amavis[127.0.0.1]:1024 by content-filter:myfilter 

and add master.cf myfilter service to pipe email to script php.

But when I restart zimbra, everything returns to default,

 content-filter:smtp-amavis

How my config change when I restart zimbra. Could anyone help me, please. Thanks so much.

Answer 1

did you check the master.cf.in ???

You must edit the master.cf.in because this is the file readed by zimbra to update the config file (master.cf). If you try to edit directly the master.cf, when restart de service the changes will be erased (because he read the master.cf.in to update changes)
