It works with any dedicated mail server.
Our filtering service is compatible with all email server types. As long as the server can “speak” SMTP using TLS v1.2, it is compatible with us. Here is a non-exhaustive list of compatible servers:
|Microsoft Office 365 (EOP)||✔️|
|WHMs (EG.: cPanel)||✔️ * (See below)|
||✖ They perform SPF verifications which can't be disabled|
| G Suite (Google Apps)
|IBM Lotus Notes||✔️|
| Novell GroupWise
||✖ Impossible to deactivate authentication verifications|
* These servers require that certain configurations be added before activating our filtering service. Our automated tests should detect any issues we could have configuring the service. Please reach out to us if you have any concerns.
We do recommend that the server be able to restrict SMTP access to only our filters in order to block “direct spam” (ie.: spam sent directly to the mail server instead of through the MX records. See the Related Articles for more information about restricting SMTP access to your server). This Firewalling can sometimes pose a challenge, especially if your server is hosted in a shared environment. If you are ever in doubt, contact your hosting provider for more details concerning IP address restrictions/firewalling for your mail server.
