Hi,
I've a little question. Is there any possibility that i can sign a subdomain with the dkim signing of the parten domain an use the same selector.
So that i don't have to add the selector so every subdomain at DNS server.
Header example:
As it is:
Domain "domain.tld":
dkim-signature: v=1; a=rsa-sha256; d=domain.tld; s=selector;
c=relaxed/relaxed; q=dns/txt; h=From:Subject:Date:Message-ID:To:MIME-
Subdomain "subdomain.domain.tld":
dkim-signature: v=1; a=rsa-sha256; d=subdomain.domain.tld; s=selector;
c=relaxed/relaxed; q=dns/txt; h=From:Subject:Date:Message-Id:To:MIME-
Should be:
Subdomain "subdomain.domain.tld":
dkim-signature: v=1; a=rsa-sha256; d=domain.tld; s=selector;
c=relaxed/relaxed; q=dns/txt; h=From:Subject:Date:Message-Id:To:MIME-
Is there any way to configure it like this or i'm on the wrong way?
regards and thank you in advance
