i didnt know where to put this, but anyway. i was trying to access my email here http://www.nei.ac.uk/Staff.asp# a few minutes ago but it wont let me login, sometimes it says access Denied and sometimes you cannot access your email account from a remote location or something, but a could login earlyer on, i dont know why i cant login now.

ISP email accounts are beginning to tighten the use of, in particular, port 25 -- the outbound connection.
Your post reads as if you can even read - see the post office.
The URL is typical of web-mail (rather than a client email reader) and suggests
membership/employee relationship. Suggest you contact the webmaster or admin help desk
to verify that remote login is still support. This could have been changed overnight.
