Not sure what you're asking. This really depends on what kind of mail you
use, and what/where you're trying to access. If you have a POP account, you
can use your mail host's webmail feature, or use something like
www.mail2web.com if they don't.
Or are you asking for something else?
Note - posting your valid e-mail address in a newsgroup post, or in your
news account settings, is a surefire way to get spam and SWEN and other
viruses sent to you....see
http://www.mailmsg.com/SPAM_munging.htm for help
in the future, but note that now that your address is out there, there's not
much you can do other than changing your address.
