[Dovecot] what is the correct password file format?

[M. Fioretti]

Hello,

I'm trying to set up dovecot installed from RPM (version
dovecot-0.99.11-2.EL4.1, the one included in Centos 4.3).

I get this error:

dovecot-auth: passwd-file(user at domail): unknown user

even if user at domain exists:

auth_userdb = passwd-file /etc/imap.virtual_users
auth_passdb = passwd-file /etc/imap.virtual_users

-bash-3.00# cat /etc/imap.v_users
user at domain:{DIGEST-MD5}thepassword:uid_value:gid_value::/absolute/path/to/virtual/mailboxes

why do I get this error? and what is the correct config format for this version of dovecot?

TIA,
	Marco
