Hi Sam,
Thanks Anton for the reply, I don't understand whether the filter rules are specified in the Config.pm file or in the postmaster filter section in the admin interface.
You can specify the filter both places. For normal filtering it's easiest to do it in Admin.
I might not have specified my problem before correctly but I wanted to know how to configure the headers in the postmaster filter i.e. how do I specify the headers that otrs watches out for in the incoming mails and how to specify the headers in the mail that will be fetched from the pop3 mail account configured(Ps. The trusted option is set to yes).
Just select them from the drop box (Admin -> Postmaster Filer -> Add). They're self-explanatory, I think. Also, there's a small documentation bit at the bottom of the page. -- Lars
