ERROR: Connection dropped by IMAP server received when subscribing to folders

[BattousaiX]

We receive the following message after trying to subscribe to folders.

ERROR: Connection dropped by IMAP server.
Query: SUBSCRIBE "INBOX.INBOX_Sent"

This happened to a client after trying to a client. We checked their quota, and temporarily set it to one gigabyte to see if it was a memory issue and it was not. Tried to restart courier-imap and this failed in fixing this issue. Not sure where to look and have searched these forums already.

1) Are you using a webmail client (i.e. SquirellMail, Horde, etc. )? If so, which one?

- Squirrel Mail

2) And/or are you trying to access the folders via Outlook, Thunderbird, Entourage, etc.?

This was in Squirrel Mail. The error occured in Squirrel mail when trying to subscribe to folders.

3) Does your cPanel account use mbox or maildir? If the latter, is this a recent conversion?

This uses maildir, conversion was performed a day or so ago.

It would help to know:

Are SquirrelMail and courier on the same server?

It may be a timeout issue. is there anything in the mail log about this?

I edited the address.

Thanks for your help.

The user went over their quota.

That's generally the first thing that I check.

You state the "conversion was performed a day or so ago.

- Is it correct to say this error started after the conversion?

- The folder structure you mention "INBOX.INBOX_Sent" doesn't sound right which can happen after a conversion.

- Have you tried re-subscribing to the folder(s), and or looking at this thread?

The issue has been resolved already.

The user was way over his quota.

Once he raised his quota the error was no longer received.

Everything works fine now.

chown -R user:mail /home/user/mail

This fixed for me
