Manual:$wgPasswordSender/ja

詳細
パスワードリマインダーのメールアドレス. 利用者が自身のパスワードを要求しているとき、我々が送信者として使わなければならないアドレス. また、他のメール通知のための送信者アドレスとして使用されます.

The installer automatically generates a value for this setting, and places it towards the top of LocalSettings.php. The generated value will often be nonsensical ("apache@localhost" or similar), so be sure to change $wgPasswordSender and $wgEmergencyContact if they are incorrect like this.

1.23 onwards
In MediaWiki 1.23, $wgPasswordSenderName has been removed (see there for more information). $wgPasswordSender however can and should still be used. After setting the email address in LocalSettings.php, you can optionally edit the wiki page MediaWiki:Emailsender to specify a "friendly name" for the password sender.

Example:

1.17 to 1.22
As of 1.17, the From: field in the e-mail is constructed from this setting and $wgPasswordSenderName. Therefore this setting should contain just the e-mail address (as per the first example, above). If it is in any other format then it will mangle the From: field. Here is an example of specifying a friendly name for the password sender:

Pre 1.17
Prior to 1.17 this setting was used as the literal string to use for the From: field, therefore anything that is valid in that field is allowed here. The above example could be achieved by using a special syntax, as shown below.

The most common use-cases were:
 * E-mail address: "admin@example.com"
 * E-mail address with alternative display name: "Wiki Administrator "

DefaultSettings.phpでの使い方
v1.5.0以上から、デフォルト値はDefaultSettings.phpで、1.4.x(この時の'Wikipedia'はv1.6.0で'MediaWiki'に変更された)で使用されたのと同じ値に最初はセットされますが、それが$wgEmergencyContactの値をセットした後ではDefaultSettings.phpの中では無視されることに注意してください. したがって、このデフォルト値は見られません（それゆえに、上記の現在のデフォルト値）. この情報は概して無関係ですが、あなたがデフォルト値をチェックするためにDefaultSettings.phpを見ているならばそれが混乱を招くかもしれませんので、ここに含みます.
