There is a filter that allows you to print the message and if your fax system has a printer interface and you set that as the default in WinPMail then this should work.  You can also set the option to "Run a program" and this forwards the message to the program.  The program can of course do anything you want it to do as long as you are willing to write a program.

The filters can key on most anything in the message headers or body to cause a selective action. 

Hello!

First I want to say "hi" cause' I'm new to this Forum.

Now here is my Question:
Is it possible to forward an email via fax with pegasus, just when it was recieved?
If yes, can i implement a filter that only special emails are forwarded?

Thank's for any help :)
