No, SIP messages are routed according to their request URI. I am not
sure if the regular expression in your if-clause was corrupted by
the E-Mail service (if not, at least a closing bracket is missing).
I suggest, you start with a simplified version of this regexp to be
sure that the then-part is evaluated at all. Use xlog() to add a
couple of debug messages to find out which routing blocks are evaluated.
