Sending & receiving emails slow to nonfunctional

Sending & receiving emails slow to nonfunctional

This evening, I suddenly realized that I was not receiving any emails.  A couple of tests that I sent myself have trickled in, but they're very slow.  Also, no emails were going out from my zoho account.  (no indication of an error, just nothing happening when I "sent" the messages, even though the confirmation popped up - the message didn't appear in Sent messages, or in my destination account)

An additional problem I've been having the last couple of days is that my emails from zoho to my Time Warner account are being bounced back. I don't know if it's on your end or theirs.
