accepted, yes, perhaps, but per rfc2821 says:
The local-part of a mailbox MUST BE treated as case sensitive. Therefore,
SMTP implementations MUST take care to preserve the case of mailbox
local-parts. Mailbox domains are not case sensitive. In particular,
for some hosts the user "smith" is different from the user "Smith".
However, exploiting the case sensitivity of mailbox local-parts impedes
interoperability and is discouraged.
