Parsing mail file

Hello there, I'm sure this question was ask 1,000 times, but I didn't find any archive about this, that's why I need help... Here is my problem: I receive mail file from my MTA (ie QMail), that works fine. Now, I would to find a class or a function that parse the mail and gives headers informations, body of the mail (even if it is a multi-part mail) and file attachments. I found nothing in PEAR library, nothing on the web, ... I don't what want to rebuild the wheel if somebody works on it and made a good job... If somebody uses a great function and want to share, I will please him... :-) Thanks for your help. Pierre
