Re: [auth48] [AD] AUTH48: RFC-to-be 9422 <draft-freed-smtp-limits-07> for your review

[Alice Russo <[e-mail]>]

Murray,
This is a reminder that we await approval from you regarding the item below. I should have written "please review and let us know if you approve the changes in Section 3, 3.3, 3.5, and corresponding reference updates."

The files have been updated to show 'February 2024'; available from the same URLs (please refresh).

Thank you.
