Hmm, good point. I don't have that condition in this ACL at all, so I
presume your point is valid... but wait, I thought ACLs were only run on
SMTP messages, not comand-line messages.

[...testing...]

Command-line messages from postmaster are accepted. Experiment
indicates that the "recipient" ACL is not run for command-line messages,
just as I expected.

Nope, no secondary MXs. But www.python.org is a separate machine from
mail.python.org, and it should probably be allowed to originate
webmaster (and maybe postmaster) messages.
