Damn, I fouind it earlier. Do a search for canonical, and/or lowercase
It's actually funny: Back in ~2000 Weitse sent several E-mails stating
that Postfix lowercased everything because he felt it was simply
unacceptable to require end users to know what CaPiTaLiZaTiOn (he even
typed it that way!) a user name was, even though the RFC specified that
the MTA be case sensitive.
Cut to earlier this year, and he decides to stop lowercasing everything...
