Description:

Microsoft currently only offers the option of capturing the DKIM on a sender address. In order to positively influence the deliverability of the newsletter, further DNS settings (SPF & DMARC, MX/A-Record) are required.

Once a subdomain is set up for Dynamics only, all necessary DNS-settings can be specified by Microsoft.

Current problem: If you only use one of the three methods, you cannot reliably protect yourself against spam, phishing and spoofing. Only the interaction of all three authentication mechanisms ensures successful protection against misuse and can significantly improve your e-mail deliverability.
