Web Hosting Smarthost
Web hosting providers face many challenges that can be resolved with simple solutions such as offloading smtp mail delivery to a smarthost (also known as an smtp relay). By doing so you don't have to worry about compromised user accounts sending email that ruins your server IP reputation and hinders email deliverability for all your customers. Our service is compatible with all leading web hosting control panels such as cPanel, Plesk, DirectAdmin, Interworx and other control panels that use the SMTP protocol to send out email.
Ease of Implementation
Implementation takes a couple steps. Simply add our SMTP server address in your control panel or email server configuration and add our SPF records to your customer domains.
If one of your users starts sending out spam, our filters will catch them and you won't need to worry about doing anything on your end.
We will block what needs to be blocked and allow your other users to send email out as needed. In a typical scenario if you were not using a service such as Sendmetric, your IP addresses would get blacklisted and it would impact all of your web hosting customers.
