Mailing lists adapted to spf long back, what hasn’t is the good old .forward and its more modern cousins that ask you to set a forward in email preferences on various webmail sites.

For instance, the 5321.from on this list is [email protected]<mailto:[email protected]>. Looking at other lists in my mailbox it’s similar. Mailing lists rewrite the 5321.from and thus does not break SPF. It does break DMARC, but that’s another discussion.
