After setting up Xeams I ran the inbound diagnostics check. Everything passed except Inbound Encryption. I have since installed a cert from lets encrypt.

How can I rerun these diagnostics.

Can I use a different cert then what is on my mail server or should they both be the same? I will be Xeams as a spam filter, my mail server runs Exchange.

Hello,

An SSL cert is typically issued against your FQDN of your network's hostname, not your email domain. Consider the following example:

• You have two email domains: exampleOne.com and exampleTwo.com
• The MX records for domains refer to mail.example.com
• Since mail.example.com is the FQDN, the SSL certificate is only needed for this name, not your email domains.

Therefore, you should get an SSL cert only for your FQDN.
