Change the way t he domain is being retrieved for sending e-mails from wordpress@..

[Woudloper]

On moment I have implemented Wordpress at ​my hosting provider in the Netherlands.

Last week they had send me an e-mail about new spam preventions they have taken as you can ​read hear (in Dutch).

What does this mean?
This means that the e-mail from should be from an existing domain, but my weblog is placed in a subdomain as followed:

http://weblog.domain.nl

The e-mail that is being generated from the pluggable function wp_mail is as followed:

wordpress@weblog.domain.nl

The problem:
The problem is, is that this isn't an existing mailaddress and thus the notifications of new comments, registrations, etc. aren't received to the to email address.

Suggestion/Solution:
Couldn't it be made possible that the e-mail from for the wp_mail function can be made customizable e.g. via the options within the dashboard. This way I can put in an existing e-mail address.

Extra:
See ​this reply on the forum of the hosting provider where they made a suggestion for the problem.

It was detected in 2.0.3. and not in 2.0.4.

There are many cases where the detected email address may be invalid, so please make this a configurable value.

I don't think this needs to be a core feature.

A very simple plugin (untested but should work fine) can be used to replace the builtin wp_mail function with one that sends from another address:

/*
   Plugin Name: Override Email Address
   Description: Allows you to override the email address used by wp_mail
   Author: Peter Westwood
   Version: 0.01
   Author URI: http://blog.ftwr.co.uk/
 */

function wp_mail($to, $subject, $message, $headers = '') {
	if( $headers == '' ) {
		$headers = "MIME-Version: 1.0\n" .
		"From: user@domain \n" . 
		"Content-Type: text/plain; charset=\"" . get_settings('blog_charset') . "\"\n";
	}

	return @mail($to, $subject, $message, $headers);
}

Replacing user@domain in the above plugin and activating it will allow you to pick the email address you want the emails to originate from.

This plugin works because wp_mail is one of the pluggable functions that a plugin can override by defining it before WordPress

Plugin.

I agree with westi. I'd rather see this implemented as a plugin than cluttering the core with an option that only a small subset of the users will ever use.

I've taken westi's example one step further and added a configuration page to it, so you can set the email adres from the admin section. (The largly untested statement still stands though)
