I am still unclear on resolving this issue.  As I mentioned, my previous
postfix with the same configuration allowed all hosts on my single(no
virtual)domain configuration to be masqueraded.  This was true for all
hosts except those specified in masquerade_domains with the ! negation.
I want to do exactly this for the new server, but mail to
u...@hostmane.domain.edu does not masquerade and receives the loops back
to myself error.  It is perplexing that such a simple issue cannot have a
simple resolution, or did something change between postfix--2.0.18 and
postfix-2.3.3?

No version of Postfix has ever masqueraded envelope recipients by default.

The solution is to correctly rewrite the envelope recipient on the
null client machines, for which I strongly recommend setting myorigin
correctly, and not using masquerading at all!

Nothing changed in Postfix, you have changed something on your side.
