Email Problems

I have read a couple of posts on the forum that explains one of the problems I have been having with logging on to my email. Intermittent issues.

However, my main issue is when using the Cox webmail for the past couple of weeks, after hitting "delete" on an email, it takes FOREVER for the delete to take place and the next email appear. It's never been this slow before, almost like a dial-up connection. Anyone know what's going on here?
