Mail suddenly stopped retrieving from my email provider...

I've now logged in and out of both the main NS control panel and NS webmail twice each (even sending and receiving a test msg via the webmail interface) but still no joy here. And still waiting on a response to my trouble ticket. It'd be nice if NS would be a bit more forthcoming.

Got tired of waiting on the ticket from yeterday and just called, was able to get through after about ten minutes hold time. Having tech support refresh the email boxes resolves the problem.

any1 else try calling and just getting dead air after y ou get "auto transferred to tech support"

fixed, as the answer says, u have to call them ..

What number are you all calling? Their automated phone system told me they had all lines busy and it told me to call back later.

had to call a few times and evnetually sat 40 mins on hold

1-800-333-7680

Had to call them, but the issue is fixed. Thanks everybody for the help!

In my case it was the help ticket. (I'll do nearly anything to avoid calling help lines.) No direct response from NS other than the initial automated acknowledgement (by email, which is pretty funny) but when I booted up this morning the email was flowing again.

I am having a similar problem since upgrading to mountain lion, but mine I am not able to send mail although receives fine. Once I go in and delete the outgoing mail smtp account and then put it back in it will work for a couple of days but then starts the same problem again.....Any fix solutions?? 😢

While I hope the refresh fix some have referred to helps them permanently, my experience has been different, and recurring. Running 10.6.8, and experiencing the "server not responding" and similar messages on an iMac, iPhone and Macbook Pro.

From my investigations it stems from NS being self-certified (not using Verisign, I believe, or others), and Mail refusing to recognize their certificate. When it doesn't accept their cert, it says it cannot connect, etc.

Temporary fixes have included restarts/complete power-downs (iPhone), deleting the account, clearing and resetting the password, etc. They have all worked at one time or another, and only deleting/reinstalling the account has worked every time.

Regardless, the problem has eventually cropped up again. Given the poor NS support, and that it's not orginating with Mail, Apple cannot help. Without moving email service to someone else, it appears we're doomed to more of the same.
