wp_mail and Subscribe2

Hi,

I’m running WordPress 2.0.4 and the latest version of the Subscribe2 plugin. My server is a Windows installation that runs SMTP.

I am not receiving any email confirmations when I add a test email. I’ve gone through and done some alert box testing everything appears to be working – it’s just when:

@wp_mail ($this->email, $subject, $body, $mailheaders);

…is called, I get the message about an email confirmation is sent but nothing arrives. I’ve checked it and all the variables are properly filled in. I’ve checked to see if it was marked as spam and nothing. It just never arrives.

Any ideas? I can and do receive e-mails for other WordPress functions, like lost passwords and such.
