I was trying to automatically add a special folder called "Spam" on
the folder list using autosubscribe plugin. The configuration is as
IMAP server: UW server 2007
Core SM: squirrelmail-1.4.11
Autosubscribe plugin; $autosubscribe_folders='Spam';
However, when a user logs in, she gets the following error message:
ERROR: Could not complete request.
Query: SUBSCRIBE "Spam"
Reason Given: Already subscribed to mailbox Spam
I am sure Spam folder was not subscribed before. Autosubscribe and
compitability are only two plugins currently installed.
