Hello
WHM / CPANEL gives the possibility to generate a DKIM signature and insert it in its own DNS or copy / paste in a third-party DNS.
This is OK if the client only sends mail using the WHM server I suppose.
But what if that client *also* wants to send (legitimate) mail through another server (often some platforms used in education that send mail "on behalf of" the end user) ?
We have already added the IP addresses of the mail servers of these platforms to the SPF record in DNS.
But if we activate the DKIM signature proposed by WHM / CPANEL in the DNS of the domain, will the mail that the clients send via another mail server ( not ours) not be rejected by the anti-spam systems?
Or is there a way to fix this?
Thanks for your help.
