I am working on a client input form using SMTP. If I enable SSL on port 587, an error is generated as follows: {"The remote certificate is invalid according to the validation procedure."} I recently installed a new security certificate purchased from Network Solutions. By disabling SSL, I get no errors, but the test e-mails never arrive. Any advice you have is welcome.
The web server and email servers are separate, so your SSL Certificate won't work. There is an alternative SMTP hostname you can use which already has an SSL Certificate bound to it. You can find it in the Control Panel by going to Email Management -> SmarterMail Manager. On your right, it should say Secure Web Interface: https://sm##.internetmailserver.net. Just use sm##.internetmailserver.net as your SMTP host, and SSL will work.
