email port setting

Hi guys,

I have been trying to send emails via a jsp and i keep finding that the port is blocked

"Could not connect to SMTP host: mailrouter.umist.ac.uk, port: 587;"

I have tried a bunch of ports 25, 465..but all give the same message. i am working on the machines in our university campus so have no access to turn off antivirus etc..

any ideas?
