#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

Hey @Vivaldi noticed that vivaldi.net is one of the all-greens on Hardenize.
I'd move my mails to vivaldi.net, but I have size worries, still use other providers, & own domain.
Do you have any plans to implement paid size plan, & features like automatic IMAP fetch, external sending SMTP, own domain management?
