SPF with hard fail in your own domain /and/ filtering that respects SPF
hard fail will almos
I've set up a subdomain lists.mydomain.de (and with regex expressions
as local part, to have unique email address per list, forgot to do that
here...) with soft spf and dmarc policies and that I only use for
mailing lists. Then I can use hard failure spf and dkim policies for
the domain mydomain.de
This kinda raises an important issue. I already have SPF/DMARC/DKIM set
up. But because I use several mailing lists, I do not have a hard fail
set up. I get SO many notices when I send email to lists that I'm really
worried about defining hard failures/rejections.
But I'll play around with wha
Assuming you own/manage your infrastructure it should be straight-forward.
Create SFP records for your domain & SMTP server, set them to either soft or
hard fail mode.
If you can, also set up DKIM signing of your outgoing mail.
Then create rules that looks for your from address in a message
