mailbox_command = procmail -a "$EXTENSION"

# vi /etc/postfix/main.cf

home_mailbox = Maildir/
# mailbox_command = procmail -a "$EXTENSION"

# saslpasswd2 -c {username}
# chown postfix.postfix /etc/sasldb2
# chmod 600 /etc/sasldb2
# vi /etc/postfix/sasl/smtpd.conf

  pwcheck_method: sasldb
  # libsasl2の場合はsasldbがauxpropになる

# vi /etc/postfix/main.cf

  smtpd_sasl_localdomain = $myhostname
