Sure, but Dan is right it's not a SMTP feature. It's just something Gmail did and was then widely copied. But it's a mail server feature, as far as the SMTP protocol is concerned the + has no special meaning, and is just a regular character in the email address.
Yes, although I did also say it was only gmail, which is apparently wrong. I'm surprised (but not displeased) the feature has been copied, given how little it is known. Since it's widely deployed (although gmail is probably big enough on it's own) I kinda suspect it's mostly useless now. If I was in the business of trading email lists, it would be pretty easy to run a regex over the list to strip off all those tags.
I really do wonder why other companies went through the effort of doing that.
