Description Superoni 2006-02-13 20:01:45 UTC
Directly e-mailing a user will not perform properly while using Windows' builtin
SMTP server (Windows 2000 Server, Windows 2003 Server).

Normal notification e-mails work such as change notifications, password reminders.

However, if you try e-mailing directly a user, it fails possibly due to the way
it formats the e-mail address by combining the wiki user name like so:

Here is a sample of a SMTP log when this happens:

2006-02-13 19:44:59 W2K-US2 HELO - +W2K-US2 250 31 SMTP
2006-02-13 19:44:59 W2K-US2 MAIL - +FROM:<> 250 46
2006-02-13 19:44:59 W2K-US2 RCPT -
+TO:<David.forester+<>> 501 27 SMTP
2006-02-13 19:44:59 W2K-US2 QUIT - W2K-US2 240 56 SMTP
Comment 1 T. Gries 2006-02-13 23:25:47 UTC
Comment: this is very dependent on the several windows versions.
Comment 2 Tom Giesberg 2006-05-02 17:16:50 UTC
Per, under Windows "the to parameter should 
not be an address in the form of "Something <>"". As such, you can address 
this by going to UserMailer.php and modify the MailAddress toString() function from:

  if( $this->name != '') {
    return wfQuotedPrintable( $this->name ) . " <" . $this->address . ">";
  } else {
    return $this->address;


  if( $this->name != '' && $_ENV['OS']!='Windows_NT') {
  [Everything else the same]

This will result in a simple email address that Windows' mail() implementation can handle.
Comment 3 Christian Blichmann 2006-05-17 12:33:15 UTC
(In reply to comment #2)
I would suggest adding the "Something <>"-style address to
the $headers variable and then modify the call to the mail()-function like so:

Start in line 118:
		$headers =
			"MIME-Version: 1.0\n" .
			"Content-type: text/plain; charset={$wgOutputEncoding}\n" .
			"Content-Transfer-Encoding: 8bit\n" .
			"X-Mailer: MediaWiki mailer\n".
			'From: ' . $from->toString() . "\n"/* CHANGE START */.
			"To: {$dest}\n"/* CHANGE END */;

And change line 134 to:
		mail( $to->address, wfQuotedPrintable( $subject ), $body, $headers );

This approach would be more portable.
Comment 4 Brion Vibber 2006-05-17 18:09:29 UTC
Have you tested that? My recollection is that the broken function on Windows
reads the value from the From: header.
Comment 5 Don R Gilman 2006-07-06 20:27:17 UTC
I followed Comment #3 and my system was able to send emails to another Win2k3
SMTP box (our relay system).
I now have two new problems (must be my fat fingers):
1. "Could not send confirmation mail. Check address for invalid characters." -
but the email goes forth!
2. Any edit of a page results in "Sorry! We could not process your edit due to a
loss of session data. Please try again. If it still doesn't work, try logging
out and logging back in."  Which doesn't go away when I logout, restart Apache,
etc.  I have a 2nd wiki- it doesn't send email (yet) but it also gives this
second error.  

I post this here as they both appeared as a result of fixing the above and wish
for others to properly execute your advice and not mess up as I have.

*** Bug 6659 has been marked as a duplicate of this bug. ***
Comment 7 Carl Duisberg 2006-07-28 19:57:31 UTC
The bug is in UserMailer.php, function userMailer(). In version 1.7.1 there are
two lines setting $dest:

if (is_array( $wgSMTP )) {
(1) $dest = $to->address;
} else	{
(2) $dest = $to->toString();

Line (1) is correct. Line (2) is wrong it causes the problem as is also
described in the code comment:
//     Note:  The to parameter cannot be an address in the form of "Something

Please change line (2) to 
$dest = $to->address;

Sorry for saving the same patch thrice. Had no SVN on my computer.
Comment 11 Rob Church 2006-08-30 13:56:12 UTC
Should now be fixed in SVN trunk, r16285.
Comment 12 sharon selden 2006-09-04 05:29:17 UTC
After using the fix in comment #7 I received this error, but email was sent
Error sending mail: mail() [function.mail]: It is not safe to rely on the
system's timezone settings. Please use the date.timezone setting, the TZ
environment variable or the date_default_timezone_set() function. In case you
used any of those methods and you are still getting this warning, you most
likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for
'-7.0/DST' instead

Neither in 1.7.1
nor in snapshot work
the problem is fixed (r16418).
Comment 14 Sjors Provoost 2006-09-10 15:19:44 UTC
I'm not sure if this adds anything new to the discussion, but anyway...
I had the same problem with 'my' windows webserver in combination with
(probably) a windows smtp server. I am running version 1.6.8 (because of php4).
The log from the smtp server reads:

9/08/06 10:41:22	SMTP-OU	52C1ABFFDBE9423DA6A4E6F230F81E91.MAI	452	EHLO	EHLO	34	96

09/08/06 10:41:22	SMTP-OU	52C1ABFFDBE9423DA6A4E6F230F81E91.MAI	452	RCPT	RCPT TO:<Zirrio <>	501 Bad
address syntax	38	24	
09/08/06 10:41:22	SMTP-OU	52C1ABFFDBE9423DA6A4E6F230F81E91.MAI	452	QUIT	QUIT	221 Bye	6	9	
09/08/06 10:41:23	SMTP-OU	B4DED6E0F5DC4D848A73A3448EA91E9B.MAI	452

Apparently, the problem is the address syntax:
<Zirrio <>
in stead of just describes a similar

I 'solved' it by changing includes/UserMailer.php around line 57

	function toString() {
		if( $this->name != '' ) {
			return wfQuotedPrintable( $this->name ) . " <" . $this->address . ">";
		} else {
			return $this->address;
	function toString() {
			return $this->address;
Can this problem also be fixed for 1.6.8 branch?
Comment 15 Carl Duisberg 2006-09-16 14:42:02 UTC
Fixed in mediawiki,
r16404, by not createing "Joe Bloggs <>" format email addresses in
windows at all (see MailAddress::toString()).
