Since $str can be very large, isn't there a performance / resource
penalty to the preg_match in order to compensate for a mistake that
is outside of RoundCube ?

Yes, this may help you with this particular sender, but the potential
is for each and every RoundCube user to pay this performance price
processing each and every message. Maybe my old-school sensibilities
are too worried about CPU time with today's CPUs.
