postfixで外部からのメールが届きません

現象

Sakura VPS postfix+dovecotでの環境において、メールサーバの移行を行いました。
内部のドメインでのメールの送受信はできるのですが、
外部からのメールが受信できません。

原因・対策をご教示頂けませんでしょうか？

MXを設定していなく届かないのか、パケットフィルタで届かないのか、Firewallで届かないのか、postfixとdovecotの設定が間違っていて届かないのか、maillogにエラーはあるのか、ないのか。 https://twitter.com/AkiraOkumura/status/1253144995197935617/photo/1
