Hi Bernhard

Thanks for your answer. My problem is that the rpm I compiled, do not include a maildroprc.

The question is: How and where do I create this file. How do I define that this is the file maildrop has to use. In my etc/postfix/main.cf I have add the line "mailbox_command = /usr/local/bin/maildrop". I believe this is the line I have to change to define which filtering file maildrop should use.

How do I create an external script to read those rules? And how do I call this? By postfix or maildrop, and how?

Sorry the many questions but I'm a newbie and not knowing that much about Linux yet.
