DKIM for custom domain

[arnada21]

Hi,

Is there any way to manually create dkim keys for mailserver.domain.com instead of mail.domain.com?

I'm familiar with DKIM keys and I found the pem file that holds the private key but I can't find where to put the selector.

Any help is appriciated!

Thanks!

but I can't find where to put the selector.

/etc/exim4/exim4.conf.template
You can use different selector like vmail and add in this dns

Sorry to necrobump this.

But I tried editing /etc/exim/exim.conf in centos7

But when I create new dkim record, it is still using mail instead of the custom dkim selector
