     Any idea why gmail uses 587 instead of the standard smtps port, which
is 465?  I wouldn't unblock an smtps port and for the same reasons I leave
the unencrypted smtp port (25) blocked.

     995, as you point out, is good for safe (for the server operator) exits,
as is 993 (imaps).  I think there are other harmless ones, too, like 123 (ntp,
though why would anyone bother to use it?:-), 989 (ftps-data) and 990 (ftps),
22 (ssh), 481 (ph), and doubtlessly some others.
