Hmm.. They do. default_mail_env format is: "storage_format:data" and
both mbox and maildir in "data" part treat it as
"path:option:option2:..". So, Dovecot above thought
"/home/hosted/example.com/users/test" was the storage format and "user"
the data part for it. You could change default_mail_env = maildir:~/ but
then Dovecot would think "user" as being unknown option..

I'm not sure what to do about this.. ':' was selected because it's PATH
separator as well, so people rarely have directories containing ':' in
it's name. Maybe it could be escaped as "\:"..
