Manual:$wgEnableEmail

Details
Set to true to enable the basic email features: Password reminders, etc.

Please note that some hosting providers (for example Hostmonster) seem to check that the "From:" and "Return-Path:" are genuine, to prevent spammers from using their accounts.

So if you want to enable this feature, you will need to:

 $wgEmergencyContact = "myHostmonsterAccountName@myHost.hostmonster.com"; $wgPasswordSender  = "myHostmonsterAccountName@myHost.hostmonster.com";
 * Find out what the correct sender is, e.g. by visiting a PHP page containing the following code and checking the message you receive
 * Let's assume the email at the previous point came through from "myHostmonsterAccountName@myHost.hostmonster.com". You'll need to change the following variables in LocalSettings.php

If sending email on your server doesn't work, you might want to try man>Special:MyLanguage/Manual:$wgSMTP#Troubleshooting email|this work-around, or just disable this feature, i.e. set $wgEnableEmail to false.

MediaWiki email is almost certainly not going to work out-of-the-box on Windows servers, and it may require additional configuration on Linux servers.

See   for information on how to configure the sending of email.
