#Email can be confusing. There's the big three -- #SPF, #DKIM, and #DMARC -- but do you know how to test #MTASTS, #DANE, #TLSRPT, or #BIMI? And what about #DNSSEC?
My colleagues have asked me the same questions, so my new#opensource #PowerShell module goes out to every sysadmin, #Office365 administrator, account manager, #mailsec worker, and help desk technician out there. MailPolicyExplainer will explain it all to you. https://github.com/rhymeswithmogul/MailPolicyExplainer
