I am having/have had this problem, too, since 2.3.1. What changed and why did it break the “Options” setting?
Is it possible that the culprit is this line:
$phpmailer->Sender = apply_filters( 'wp_mail_from', $from_email );
in pluggable.php that wasn’t there in 2.3? I think it may have changed how the intermediate mail servers perceived the messages…
see this bug trac ticket for a clean resolution.
Well, I created a “wordpress” e-mail account at the domain and it still doesn’t send the comment notification e-mail. I tried deleting the line from pluggable and that didn’t work either. So I don’t know what to do. Any suggestions?

After I upgraded to 2.3.1 I ran into a comment e-mail notification glitch. First, when someone entered a comment, the e-mail was now sent to the e-mail account “wordpress” rather than the admin contact e-mail account I listed within WordPress. Second, it was being sent to the ISP’s assigned hostname, not the actual URL of the Web site. [My ISP assigns a sub-domain type URL for accounts that are created before there’s an actual Web address. In this case, gdwallen.securesites.net instead of http://www.ifoapplestore.com.] Turns out I couldn’t add a “wordpress” user to that Web alias. So I went into the ~/wp-includes/pluggable.php file and changed the “wordpress” reference to “root”. That sent the e-mail to an account that I could access. I don’t know why the e-mail address changed or why it was picking up the hostname from php internal variables. But that’s the fix.
