Email Notification Plugin (Watershed) – Errors

Well, I’ve gotten it down to activiation of the Watershed email notification plugin (current version 2.3.1), and got a port error for SMTP, so I tried the ini_set() idea. Now, no errors, but after testing the plugin by emailing the subscription list, I see “Message sent to 0 people”, although there are three emails listed with YES under the “subscribed” column. Why won’t it send? Apparently I’m accessing the correct port by using the ini_set() command, because I’m getting no more errors. Any idea? This is the ini_set() used in block_send_email.php:

ini_set(”SMTP”, “localhost”);
ini_set(”smtp_port”, “25″);
