Toot

I manage a mail server for a small organization. Ordinarily it just runs perfectly, but one thing it does is forward email to private lists, and an increasing number of sending email services are using a "hard fail" setting in their SPF record, which interferes with DMARC and SRS forwarding. This isn't really a problem in the standards - it's a problem in the knuckle-dragging administrators who set up their mail servers incorrectly. https://www.mailhardener.com/blog/why-mailhardener-recommends-spf-softfail-over-fail
