I can't see any operational reason to block 587.

We had a client whose RFP vanished into thin air because of
that-- he sent
it from a hotel that practiced port 25 hijacking and had had
their IP
blacklisted for spewing much spam and viruses. So our server
rejected the
message, and when it tried to send the NDN to him *his*
server rejected the
NDN for the same reason. Fortunately he called the next day
with some
details he'd omitted....
I recommended he go back with an army of Huns and raze the
hotel, but he
settled for a nasty letter and using 587/TLS in future.
