This has been going on for about a month now.

It is getting worse.

I have important email that I need to access and this is a problem.
The username/pw login process is fine, but once you select Horde/Squirrel Mail/Roundcube - the browser just sits there until the error shows up.

ERROR:
ERROR: Connection dropped by IMAP server.

It does not seem to be related to any time of day; this is happening any time, day or night.

I noticed another posts about this with no resolution listed.

Any suggestions are welcome.
