It's not just mail. These days the mantra seems to be "only allow port 80 and 443 through, the users don't need anything else." specially in situations you cite (public wifi, hotel nets etc.). In these cases, i believe even ssh won't go through. Default settings in some devices don't help either. I remember that until a few years ago, port 443 traffic was getting blocked, but enough stuffs stopped working, that 443 is now allowed everywhere. Personally, have been lucky using smtp+ssl on port 465. Doesn't work 100%, but works most of the time. thanks - gaurab -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHG3jiSo7fU26F3X0RAmNWAKDoxlwaivgeKGPvczL5FpgyOV8eFgCfW2iZ 0d0ZTyWFQA53mdbSNAryYHE= =VZUx -----END PGP SIGNATURE-----
