I\'m currently working on a system that allows users to reply to notification emails that are sent out (sigh).
I need to strip out the replies and signature
I don't believe you can do this reliably (signatures used to begin with '--'
but I don't see that anymore). Perhaps you're better off asking people to reply inbetween text headers and then simply strip the reply from this ? It's not elegant, but perhaps more reliable.
e.g.
REPLY BETWEEN HERE -->
AND HERE -->
so you'd simply look for the required headers above and take what's inbetween.
