What is official policy on submitting FP's?  Description and packet
captures?  But to what address?  Where to send them,?

The original rules are designed to catch a buffer overflow with an
overly long 'Content-type:' or 'Content-encoding:' tag.  The current
signatures are looking for those content strings, followed by 200
bytes of  [^\r\n].  Several webmail clients are causing FPs on this
sig, the text they actually return is delimited by <br> notation, or
with AOL they are sometimes delimited by the literals "\r\n" (format
string?).  At any rate, the expected <cr>/<lf> terminators aren't
there, and the sigs fire.

Can you send an example packet that shows the FP?
