No. Postfix has no authentication methods on its own.

Yes.

# Certs
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem

# Dovecot 2.x
# For postfix to talk to:

service auth {
  unix_listener /var/spool/postfix/private/auth {
    mode = 0666
  }
}

# allow IMAP only
protocols = imap

# For IMAP users to get their mail

service imap-login {
  inet_listener imaps {
    port = 993
    ssl = yes
  }
}

# For SQL users to authenticate
# Note that UID and GID and mail_location are for MY system
# if all your users are in sql, you can get mail_location from
# the database

userdb {
  args = /etc/dovecot/dovecot-sql.conf.ext
  default_fields = uid=vpopmail gid=vchkpw mail_location=/usr/local/virtual/%u
  driver = sql
}
