Well you have other email ports to exclude when Vuze is communicating or actually downloading.
Port 137 isn't an email port (UDP NetBIOS).
25, 110, 119, 143, are the standard email ports, these are certainly needed. But I believe you should also add the secure email ports 587;993;995;465 as it certainly won't hurt. This will ensure no attempt by avast to redirect what is a secure email port (causing this type of notice) and an effective failure as avast would be expecting the corresponding email Protocol and not P2P.
