We discussed this a couple months ago, although I didn't go dig up the
discussion; the upshot is that the MTA usually accepts any mail as
long as there is *some* recipient. SM's original assumption was
apparently that you had to have a To:, and this commit that you found
was done because someone realized that they could send Bcc:-only
messages through their MTA. The same is true with Cc:-only messages,
and I don't think it's up to us to guess why the user would do that.
I think removing arbitrary restrictions is the Right Thing. :-)
