Hi! In advance, thank you very much for your time and understand that my English writing skills are not the best!
My problem lies in the configuration of DKIM.
Currently we have 7 DNS records for mail and our email infrastructure is under Microsoft Exchange.
All mail is transmitted to MEG through a Cluster of HUBs. The emails from our internal users (can be 7 different DNS domains) are sent to the MEG by the same Cluster HUB.
The HUB Cluster is presented to the MEG with a single IP address (the VIP of the cluster).
When wanting to set up DKIM, the wizard prompts in the first step to enter a domain (does not accept wildcard). Thus, I can only configure one domain (of the 7 we have).
Try to generate a profile of DKIM, but when setting the criteria can be selected only related to hostname (source / destination), VLAN and finally IP (source / destination) choices, but in any condition you can select "Domain".
Honestly I do not find way to how to set this for all my domains. Earlier, another product we could configure DKIM signature for all domains using the DNS domain as the criterion.@
