I don't know about any vulnerabilities, but one uses of uris like the ones
above which you might be interested in knowing about (and which I use myself
occasionaly) is to pass query string or path info to be appended onto the
new uri comming out of mod_imap.  Browsers as a rule do not treat something
like <A HREF="/"><IMG .. ISMAP></A> consistently at all.  Some
retain the query information and many just drop it.  The only reliable way
to pass additional information is to add path information to the end of the

The requires some magic on the server end to be of any use and it is unlikely
that even if you did have that functionaltiy that anyone else would know to
use it.  Did you happen to catch the agent id or the referer?
