If I recall the RFCs correctly, the right hand side of e-mail
addresses are indeed case insensitive, but whether the left hand side
of e-mail addresses are case sensitive or not, is up to each domain.
For example, foo@bar.com does not necessarily equal FOO@bar.com.  This
means that, in general, case must be preserved.

What is relevant to this discussion is, I guess, that deciding between
case sensitive and case insensitive is a trade-off, and there is no
clear answer.
