Hello,
Did you find this error in your qmail log files?
This is a temporary error that may or may not be a problem.
Possible causes include the remote mail server bring down or a network between between your server and the remote mail server.
I recommend watching for persistent problems that may need you to take action, but more than likely this problem will fix itself.
