icloud.comやme.comやhotmailにメールが届かない時

More than 5 years have passed since last update.

iCloudの場合下記が原因のことが多いようです。

mail.add_x_headerがONだと届かない模様

vi /etc/php.ini

mail.add_x_header = On
↓ 変更 ↓
mail.add_x_header = Off

/etc/rc.d/init.d/httpd reload

確認

php -i |grep mail.add_x_header
mail.add_x_header => Off => Off

qmailで、icloud.com や me.com や hotmail.com などにメールが届かない時。

/var/log/maillog

deferral: CNAME_lookup_failed_temporarily

こんなログが残る。qmailのパッチをあてて、DNSパケットのサイズが大きくても受け取るようにしたら治るらしいのですが、パッチを適用しても、メールがとどかない場合が有ります。

本来の使い方ではないと思いますが、その場合にどうにかしてメールを、送信する方法

/var/qmail/control/smtproutes

こちらに下記を追記

nifty.com:smmx.nifty.com
icloud.com:mx1.mail.icloud.com
hotmail.com:mx1.hotmail.com

なぜか届くようになります。
