Yes. Authenticated SMTP makes tracking down which of your users is doing the spamming easier. But you're assuming that SMTP AUTH isn't being used on port 25 already. You can do SMTP AUTH just as easily on port 25 without having to re-educate your users and still net the same simplified tracking procedures that you mention. It sounds to me like what we should really be talking about is getting MTA operators to begin using SMTP authentication of some kind (any kind!), rather than harping on whether or not MTA's should accept mail on port 587...
