Well, yes, but the relevance of ident to that would be purely
on-campus, which is why (having thought about it for a moment ;-)
I decided not to mention the issue here.

If multi-user-system(0) spoofs mail to on-campus MTA(1) which in turn
pesters some external MTA(2), there isn't much that the admin of
MTA(2) is going to get out of an ident request, is there? As for
actions taken by the admin of MTA(1), you "have ways of" dealing with
on-campus abuses (evil smirk).
