[opensuse] How do I pipe to program in Evolution

I have one person whose email comes in periodically from the list which has bad headers making it appear blank until I check source. I can filter the email but I need to pipe it to a program. I need to know if this program can be Perl or Python and if I can use it to correct the email or If it must be done in C, C++. Such that if the email comes from this person I pipe it to the program and then continue to process normally.
