It could be SELinux:

% matchpathcon /home/anyone/mail
/home/anyone/mail       unconfined_u:object_r:user_home_t:s0

You might need to make the mail directory be named Maildir:

% matchpathcon /home/anyone/Maildir
/home/anyone/Maildir    unconfined_u:object_r:mail_home_rw_t:s0

I suspect that Dovecot isn't allowed to create 'mail' but is allowed
to create Maildir by the default policy.
