[SM-USERS] Very Bizzare Problem

[Chris Burton]

Hi

I have recently (in the past 4 weeks) been having very weird email problems with my OS X server, so as a quick fix i had been pointing people to use our web mail system of Squirrel Mail version 1.4.3a this was working fine up untill about 2 weeks now i am getting the most bizzare problems, i have pasted the problems below, can anyone shed any light on helping me get rid of these errors.

ERROR : Unknown imap response.
Query: FETCH 1:* (FLAGS UID RFC822.SIZE BODY.PEEK[HEADER.FIELDS (Date To Cc From Subject X-Priority Content-Type)])
Server responded:

and also

ERROR:

ERROR : Connection dropped by imap-server.
Query: LOGOUT

i have not changed anything on the server to cause this happening. i am really really confused
