Hi,
The args parameter of userdb contains scheme, username format and location
of the password file. Please take a look this link
https://doc.dovecot.org/configuration_manual/authentication/passwd_file/
For example, mine is:
userdb {
driver = passwd-file
args = username_format=%u /etc/dovecot/imap.passwd
}
$ head /etc/dovecot/imap.passwd
to@localhost.local
:{plain}1:vmail:vmail::::userdb_mail=mdbox:~/Mdbox/%d/%n:INDEX=~/indexes/%d/%n
