*sigh*

So this is a non-RFC compliant ""feature.

Nope.  The LHS of an email address *is system defined*; no one outside of
the destination mailserver is permitted to make any assumptions about it.

RFC5322 3.4.1:

"""
The local-part portion is a domain-dependent string.  In addresses,
it is simply interpreted on the particular host as a name of a
particular mailbox.
"""

Note that using a "real name" as an email address is Not The Best Idea:
