How to check/test DKIM records for my domain?

To check/test if you have published a DKIM record correctly on a domain, you can verify DKIM from the following website, https://dmarcian.com/dkim-inspector.

1. Enter the domain name for ex: vtiger.com in the domain field.
2. Add the selector(vtigermail) in the Enter Selector field, In Vtiger we use vtigermail as a selector.
3. Click on Inspect DKIM.

Note: Vtiger strongly recommends you add a DKIM record for both ad-hoc emails and email campaigns. DKIM record is mandatory.
