[AusNOG] Is anyone on ausnog from gmail

[Brad Eckert]

The way this was implemented is very frustrating. I assisted a few orgs
that, I had done consultancy for prior. But many out there are only just
now, going to notice and go WTF?

And these are not black and white, meaning that is you move into a
"compliant" state with regards to SPF, DKIM and blah signed TXT records.
The  "reputation" of the now tainted domain will take some time to correct
itself.

Google will not resolve this. The reputation will need to build back up,
you can email my address direct. As I have Google Workspaces Enterprise
with all the verbose logging for mail. Validating the delivery to gmail
workspaces vs vanilla freemium gmail accounts would be interesting.

You could also build a sub domain, marketing email comms often use this
method of sending via noreply at info.example.com .. default policy  allows
then penalises if you do not tick the boxes (there are many others beyond
just TXT signing .. reverse-dns etc.

Could this all be a ploy to nudge small to medium biz to sign up for Google
Workspaces as their business fails without email ? hmm

Regards,

Brad
