Did you check the permissions for the /tmp ? It might not be set correctly or have gone Read-Only.
Also , check whether there is enough free space available in that.

[crazyaboutlinux]

no i didn't which permission should be /tmp ?

[Andrew Boring]

/tmp should be something like:

drwxrwxrwt 8 root root 11264 Apr 24 10:30 /tmp/

You can do the following if it's not:

chmod 1777 /tmp

If it's read-only, then you'll need to delete the tmpDSK and recreate it.
Test that with:

cd /tmp
touch file

However, the "connection dropped by IMAP server" error in Squirrelmail is frequently resolved with:

yum install gamin

[crazyaboutlinux]

its working fine without doing anything however i would like to inform you that it was due to backup running process on our server that's all.

thanks for updating your suggestions
