Looks fine to me.
What SMTP client is it by the way that treats a 535 in response to
AUTH as a reason to bounce the message, and would retry with a 4XX?
Postfix these days defers mail when authentication fails whether
the error is 4XX or 5XX.

The patch may be "more correct", but if MTAs generally understand
that SASL failure is "always" transient (either the client is
misconfigured and should not be using SASL, or authentication is
requirement and the details are misconfigured) then the patch is
perhaps unnecessary.
