I agree, but unfortunately I'm in the minority.  It appears that google
has gone down the path of blocking mail that doesn't pass these
stringent tests and I now cannot see my own postings to lists such as
this one or certain others who post.

Spf testing on from: is not dokumented as spf, but sender-id, maillists that checks sender-id should really check dkim instaed

I fear mailing lists have to start munging the From: header now by
adding their own domain name on the end.

Check dmarc=pass on users here on this mailllist shows that mangling from is incorrect or unneeded

Does google really use a patched sid-milter ? :)
