managesieve / sieve - append dot prefix on moving mails into folder

[Martin Johannes Dauser]

Hallo!

If you didn't define a separator it's default is "." . So you would need
to change "INBOX/Monitoring" to "INBOX.Monitoring" to be accepted.

And 10-mail.conf needs a "prefix=INBOX." --note the dot as a separator
at the end. 

Hope this helps
Martin
