Mailer Error: Could not instantiate mail function.

[pia]

Here is what I get when I try to send a test message.

1727 del send 2007-03-23 09:38:59 Error sending message 9 to user@address.com (user@address.com)

1726 del send 2007-03-23 09:38:59 Mailer Error: Could not instantiate mail function.

I am using phplist version 2.10.4 on a windows server 2003 server. I am using another smtp server on the local subnet to send the mail. I can use outlook express to send mail from this windows server to anyone and it works.

This is the only smtp setting I have configured.

define("PHPMAILERHOST",'192.168.1.6');

I have searched through a lot of posts here and really didn't see anything that could fix this.

Any Ideas?
Thanks,
John

I found something that said change line 44 in admin/class.phplistmailer.php

From:
$this->Mailer = "mail";
To:
$this->Mailer = "sendmail";

and now phplist says the e-mail was successful but I never get anything and don't see the phplist server even make and attempt to connect with my smpt server.

Did you disable test mode in config.php, as described in the FAQs?

If the problem persists, you could try to enable SMTP in config.php and -in that case- also take a look at this report: http://mantis.phplist.com/view.php?id=8590

Thank you so much for directing me to this!

This is what helped it work.

So I did a quickfix and replaced the problematic line
if (!$this->Host || $ip == $this->Host)
with this one:
if (!$this->Host)

Again, thanks a lot for your help!
