Or they might have an email address but it not be .edu - in the UK they're .ac.uk for example. Used to annoy me when US sites would use email to validate my studenthood and then miss it anyway (and the service was supposed to be available here).
Oh that makes me think of another: Anyone with a university email address is still a student/faculty member!

At least you have a common suffix. Around here, a student at the computer science department of the federal university of the Rio de Janeiro state (UFRJ) could have an email at the domain dcc.ufrj.br; yes, universities which got on the Internet early enough have their domains directly on the ccTLD.
No common suffix for universities either in Germany. And at my university, comp sci students didn't get just one emeail but a second one administered by the comp sci department.
Actually, it does seem that they have a .edu now. I guess those aren't restricted to US-based institutions anymore?
Oh that's impossible to deal with then. Mine at least changed to @alumni.imperial.ac.uk (vs. @imperial.ac.uk) - so you could exclude me (now) if you really wanted to go all out.
