I'd say to check the control panel for any note of it. You can also just randomly try URL's such as yourdomain.com/webmail or mail.yourdomain.com. Your host would also be able to tell you.
Jordan, thank you!
I just typed in www.domainname.com/webmail and that was it! It gives you an option of two interfaces that come with cpanel. Both are really unpleasant looking by the way... 🙂
That is an AWESOME looking web site and amazing service.
I was a little skeptical at first to input my account name and password, but then I just tried, and it looks amazing.
I've used it many times in the past Art. I have a couple of ISP accounts that didn't allow web access in the past so it came in handy.
No security issues or anything.
I've even used it when I was having DNS problems on a site and could reach the email directly.
