Hello,

In which mode is DKIM supported?

Is DKIM supported in the free version?

Is it possible to install Xeeams on CentOS 7?

With regards,

Emile

Emile,

DKIM is used for both inbound and outbound. For inbound emails, it validates the signature for incoming emails. When sending outbound emails, it signs outgoing emails with your signature. It is supported in all 3 modes (stand-along, firewall & hybrid)

DKIM can only be used for outbound emails when using the Community Edition, unless you have less than 5 users. Once the number of users go beyond 5, filtering will be disabled and therefore, DKIM will not work for inbound messages.

Yes, you can install Xeams on CentOS

I'm running the Enterprise version of Xeams with one user and outgoing DKIM signing stopped working when I switched from the Community edition.    Do any changes need to be made to get this working?   I had removed and added the domain back to the configuration and it's listed with the thumbs-up but DKIM information is not being added to outgoing email - SPF and DMAC is working

Switching from Community Edition to Enterprise or the other way around should not have any affect on DKIM.

Try running Diagnostic Tools - Outbound under the Tools menu and let me know the results. I also recommend sending an email to our support department so I can confirm if DKIM is missing and ensuing your outbound email went through your Xeams and did not bypass it.
