Znuny Open Source Ticketsystem

What/where are PostMaster prefilters and how can I change them?

Crythias,
It may not be a strictly OTRS issue, but do you have any idea how that might be done?

I don't think that will work. It needs to edit the actual email subject and body before the email is entered into OTRS. What is the script that actually creates a ticket from an email, and what is the script that actually harvests emails for OTRS?

I see why you directed me there. However, in order to change it the way I'd like, I need to access a MySQL database for information, therefore I think I'd have to edit the actual script perhaps.
A list of customers is in the MySQL database, and I want to check that list, see if the email is ...

Where is that located?

I would like to change the way tickets are added into the database. When support emails are fetched from the server and entered as tickets, I'd like to change the subject and body of the emails/tickets. How can I do this, or what script should I edit to do this?
