For german universities it is common to block port 25, as lots of students
don't care a lot about their computers security and lots of spam and worms
were sent from university IPs.
However no university known to me so far blocks port 587, and a customer of
mine at the university of Erlangen happily sends mails using port 587 as far
as I know...
Blocking port 587 also would not make much sense, as usually authentication
is required. At least I am sure that the Saarbrücken university does not
block it.
