I often get a message after sending an email, and i'm not sure that it went out or not.

"Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.

Details:

This IMAP command could not be sent to the server before the connection was terminated.

Server: imap.gmail.com

Protocol: IMAP

Port 993

Secure (SSL):1

code:800ccc0f

I don't think that it is due to long periods of inactivity, and I don't seem to have any other server or network problems. It pops up quite often.
