メールサーバーにメールを受信できません

このチュートリアルに従って、メールサーバーを作成しました。
https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql

メールクライアント、SMTP、IMAPでメールを設定しましたが、両方の接続が機能しています。自分のメールアドレス([email protected])から別のアドレス([email protected])にメールを送信でき、それを読むこともできます。しかし、自分の電子メールサーバーの電子メールアドレス([email protected])に送信すると、送信されますが、example @ domain.comの受信ボックスに表示されません...

Mxレコードを作成しました:example.com mx 10 example.com
そしてspfレコードも作成しました:v=spf1 a mx ~all

メールサーバーはUbuntu14.04.1デスクトップ上にあります。

私の質問は、メールを送信したのに、なぜメールに受信トレイが表示されないのですか?私もPOP3で試してみました...

この解決策を見つけました:

これを/etc/dovecot/conf.d/20-lmtp.confに追加します。

protocol lmtp {
postmaster_address = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf # required
mail_plugins = quota
}

おそらくこれは:

protocol lmtp {
  # Space separated list of plugins to load (default is global mail_plugins).
  #mail_plugins = $mail_plugins
}
