I wouldn't be the reputation of a crooked politician that nobody uses case sensitive local parts. The golden rul for e-mail is to use the address that the intended recipient gave you and don't try to make it prettier.
Reading the RFCs isn't dangerous; reading urban legends about them is. RFC 5321 and 5322 don't require that the local part be case sensitive, they simply permit it. -- Shmuel (Seymour J.)

And one of those rare exceptions is itself exceptional: the left-hand part of an email address (the "lists" in "li...@akphs.com") is theoretically case-sensitive per the RFC. But sanity prevailed, and nobody but nobody implements that way (sure would have made mainframe email fun!). So if you're digging into the RFCs, beware. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
