It's not really a problem from that perspective, as long as it
requires the user to be logged in. The mail would be sent from the
users account, with that one as a sender, and thus be exposed to the
same moderation rules as the rest of the list posts.

Said bot can already use the bug report form *without*  having to sign
up for an account.

Or said bot could submit news or events, which trigger an email to at
least some lists, which hasn't bene done.

It's supposedly not easy for a bot to sign up for a community account,
since it requires you to have access to the email address it's
registered on. If that doesn't work, it's a bug and needs to be fixed
regardless.

We've already solved that problem for other situtations, and given how
the infrastructure is built, that's fairly easy to replicate to
another node.

I think the bigger problem is "who'll write it". AFAIK, the CF app
*itself* is even more person- and time-constrained to senior
developers (Robert Haas only) than the infrastructure, and that's a
bigger problem. There are already a bunch of things that are a lot
simpler than this that has been pending on that one for well over half
a year.

I think DKIM was a bad example, because AFAIK our lists mangle DKIM
and thus actually show them as *invalid* for at least the majority of
messages...

That would be neat.

And FWIW, I'd find it a lot more useful for the CF app to have the
ability to post *reviews* in it, that would end up being properly
threaded. The way it is now, half the reviewers create a *new* thread
to post their reviews on, making it a PITA to keep track of those
patches on the list at all, which somewhat takes away the whole idea
of "mail being the primary way to track it". Not saying it's critical,
but I'd put it a lot higher on the list than being able to post the
initial patch.
