Dovecot, не могу подключиться telnet-м

# Database driver: mysql, pgsql, sqlite

driver = mysql

# Examples:
#   connect = host=192.168.1.1 dbname=users
#   connect = host=sql.example.com dbname=virtual user=virtual password=blarg
#   connect = /etc/dovecot/authdb.sqlite

connect = host=10.5.1.249 dbname=mailserver user=mailuser password=sans

# Example:
#   password_query = SELECT userid AS user, pw AS password \
#     FROM users WHERE userid = '%u' AND active = 'Y'

password_query = SELECT email as user, password FROM virtual_users WHERE email='%u';

# For using doveadm -A:

iterate_query = SELECT userid AS username, domain FROM users

user_query = SELECT home, uid, gid FROM users WHERE userid = '%n' AND domain = '%d'

use:
userdb static {
    args = uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes
}
to tell Dovecot where the mailboxes are located. This is similar to the mail_location setting. The user gets authenticated in the "passdb sql" section. So the "userdb static" section defined where the mail folders are located. Using "userdb sql" is not needed as all mailboxes follow a fixed directory schema. This saves an SQL query for each access. The "allow_all_users=yes" setting means that it is not necessary for Dovecot to check if a certain user exists. We can do that because Postfix has already ensured (in the virtual_mailbox_maps query) that the users existed before their email was handed over to Dovecot's "deliver" agent.

You will want to comment out the section called "passdb pam that deals with system users. Otherwise Dovecot will also look for system users when someone fetches emails which leads to warnings in your log file.
