Hi there. I'm not able to download emails from Zoho into my mail client. I've suddenly started seeing the following error:

"The server returned the error: The connection to the server “imap.zoho.com” on port 993 timed out."

I'm using Apple Mail Version 4.5 (1084) and I've successfully used it for several months now. None of the mail settings in the client have changed so I'm a bit perplexed. Note that I'm able to send email just fine. And I can check messages on the web interface as well. It's the downloading to the Mac client that isn't working.

I'd appreciate input.
