I'm running the Open Source edition, version 6.0.3

The system has been running fine for the last 2 weeks now, and this afternoon this problem started...

Is there anything I need to check or do?
I already tried restarting the zimbra service through

/etc/init.d/zimbra restart

which didn't resolve the issue...

Thanks for the help and info!

I'm using the Yahoo Zimbra desktop 1.0.3 & am having the same issue. I have 6 email accounts: 3 pop accounts, 2 yahoo accounts, & 1 Gmail account. On 2 of the 3 pop accounts I get a red exclamation mark stating "Failure communicating with remote server. Please try again later". I seem to be getting emails none the less in those accounts via Zimbra but I wonder if I'm getting all of them due to this error message. BTW, the 3 pop accounts are from the same domain, yet only 2 of the 3 are having the problem. Any ideas?
