Postfix：554 5.7.1リレーアクセスが拒否されました

Question

私の問題はこれです：メール（evolutio@lars-dev.de）から@gmail @web @gmxなどの他のメールにメールを送信できます...

しかし、GMailからevolutio@lars-dev.deにメールを送信しようとすると、エラーが発生します。

Delivery to the following recipient failed permanently: evolutio@lars-dev.de Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain lars-dev.de by mx1.cw4.me. [195.138.240.200]. The error that the other server returned was: 554 5.7.1 <evolutio@lars-dev.de>: Relay access denied

ドメインのMXレコードがPostfixサーバーに設定されていない場合は、MXレコードを適切なSMTPサーバーに設定する必要があります。あなたの場合、サーバーmx0.cw4.meです。 MXとして設定され、このサーバーはlars-dev.deのメールを受け入れません。

$ Host lars-dev.de lars-dev.de has address 195.138.240.218 lars-dev.de mail is handled by 0 mx0.cw4.me. lars-dev.de mail is handled by 0 mx1.cw4.me.

多分これはあなたのホスターのMXであり、このサーバーはlars-dev.deのメールを受け入れません

$ telnet mx0.cw4.me smtp Trying 195.138.240.200... Connected to mx0.cw4.me. Escape character is '^]'. 220 mx0.cw4.me ESMTP Postfix (contentWays Infrastructure - www.contentways.de) ehlo rene 250-mx0.cw4.me 250-PIPELINING 250-SIZE 512000000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN mail from:test@test.com 250 2.1.0 Ok rcpt to:evolutio@lars-dev.de 554 5.7.1 <evolutio@lars-dev.de>: Relay access denied

上記のTelnetセッションでは、ホスティングサーバーがlars-dev.deのメールを受け付けないことがわかります。
