mail()'ing to multiple addresses?

[Anon]

I'm running php as CGI under IIS 4.0 on NT. Trying to get mail() to work has given me all sorts of problems... Here's the latest/greatest...

I can't get it to send mail to two addresses in one call to mail(). Here's some code, which should work... but it doesn't, apparently:
mail("user1@domain1.com,user2@domain2.com","subject","message");

I've tried so many different ways of formatting the from string it isn't funny... I've tried with and without <>'s, with and without commas or semicolons... lots of different things. I read RFC822 (on formatting email, basically) and it says that the string right there should be fine... But no.

With some strings (that one being one of them, I believe) I can get the email sent to the second address... but never the first.

In php.ini, SMTP and sendmail_from are set appropriately.

The smtp server is running Solaris. I'm not sure what it's running for smtp. I think it's sendmail. (We tried installing sendmail on the NT host and setting SMTP=localhost, but that just locked up on the mail() function every time until it timed out...)

Any tips would be greatly appreciated, of course...

Thanks.

Since you use IIS4, there may be a quick fix you can apply:

(1)Enable the SMTP on your IIS4 and use CDO for NT to send emails.
(2)Connect to the CDONTS component:
Here is an example:
<?
$email = new COM("CDONTS.NewMail") or die "Could not create e-mail");
$email->to = "name@domain1.com, name2@domian2.com,...name_n@domain_n.com); $email->from = "me@localhost.com";
$email->subject = "just a subject";
$email->body = "just a message";
$email->send();
?>
