Hi,
I see some ESP are using the selector to do domain reputation.
In what way? Given that the selector is an opaque string, are you
reading something into their choice of selectors that isn't there, or
are they documenting that they intend meaning for their selectors?
We used to have a reputation based on the IP, but with DKIM based
reputation, it is more difficult to have a granular reputation,
therefore the use of the selector to differentiate emails.
Is the use of the selector for this purpose codified somewhere?
"Don't do it. Use a subdomain."
Cheers,
