Thanks a lot for your answer ! I'm sorry for my delayed reply but I have seen your message today only.
I can confirm that your solution run properly but now I'am confused because : 1 - The mail has not passed TROUGH the pipe but simply it was sent TO the pipe. In this situation I cannot change the the mail header as like as spamassisn or bogofilter, without a specific plugin. 2 - Since the difference between the two scripts is that tee opens an output stream too and the file is empty, i suppose that if the script produces output it is killed. This does not seem to be a desired behavior. Bye and thanks again. -- Evolution Filter Pipe does not work https://bugs.launchpad.net/bugs/311562 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evolution in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
