I also use the + with GMail as well as my own email and often find it is rejected. What a bunch of morons there are out there designing email address validators.

Good on them. I’ve known for a long while that ‘+’ is a valid address “atom”, as RFC 2822 calls it, but the plus sign is still interpreted by most website forms as invalid. So I gave up the battle nearly a decade ago, actually, for my own email address.

Email delivery must be near 100% reliable, in terms of giving a usable recipient address, for people to continue to use it. If a website form chokes on the ‘+’ and doesn’t tell you, you might never receive the acknowledgement mail, etc. Doesn’t happen that often anymore, as *most* forms now hand off to solid email-delivery components (JavaMail) or backends (sendmail, postfix) that don’t choke… but FYI.
