    When a single user trys to log into webmail via squirrelmail, she is greated with this error

    ERROR : Connection dropped by imap-server.

    and I have no idea what is causing it, I read on the internet that it could be caused by a big mailbox, and i checked and this is true she has about 70MB in her mailbox spread accross various folders, so I dont think this can be causing the problem.

    Other people suggest that it could be due to having a corrpt mailbox altogether but I do not know how to reconstruct the mailbox, so can someone tell me how to do so with the above setup, or can they point in me the right direction on how to fix the problem.

    I notice that in the web interface it says INBOX (130) as there are more and mroe emails going in, but, sadly i cannot see them.

    Please ay suggestions, solutions will be great
