[Dovecot] Cannot use userdb to update Maildir

[e-frog]

>  more /home/dovecot.passwd
> health:$1$MCtvt/Tz$FmKqU/cbWlBhKnhc5W.Ko.:1152:1152:/home/health:userdb_mail=mai
> ldir:~/Maildir

I guess you need two ':' between 1152 and /home/health and userdb_mail=maildir:~/Maildir

So the line should look like this:

health:$1$MCtvt/Tz$FmKqU/cbWlBhKnhc5W.Ko.:1152:1152::/home/health::userdb_mail=maildir:~/Maildir
