But it doesn't, apparently. I see no evidence of a failed callout in
my log when I send you (Ian) a test message. I must be missing
something. (rereads...)
Ah! You do the use_sender callout only if the normal callout doesn't
work. That's why my message got through.
Still, ISTM it doesn't make sense to try use_sender as a fallback (as
opposed to use_postmaster) since it is entirely reasonable for sites
to block spoofed local sender addresses.
