This is correct rfc behaviour, the user name part of the email address must be left unchanged, only the system storing it can perform case-transformations on it, as opposed to the host, which should be lower case, but as most email providers are cese-insensitive (is anyone case-sensitive?)
Per the spec: LHSs of mailbox names have case sensitivity that is implementation-dependent and must be treated as case-sensitive.
RHSs of mailbox names are -- these days -- domain names, and domain names are case insensitive by their spec.
Well, that's what i said, or at least intended to.
I misunderstood you to be talking about RHSs. LHSs *must* be treated as case-sensitive, regardless how many providers don't actually do it that way.
RFC 2822 and 1136, I think.
My think is that they're 821 and 2821 :-)
The case-insensitivity of RHSs devolves from the DNS RFCs, so neither 2821 nor 2822. RFC 1035, actually, s 2.3.3.
