Gmail +snes9x tagging does not work

[Knight_Captain]

Hello,

I tried to register as example+snes9x(at)gmail.com but that seems to throw off the forum software, and no confirmation email gets sent, so I had to re-register with another email address.

Unfortunately I doubt there's anything that can be done about that. Nothing is set on our side (that I am aware of) that would stop that. I do see the account you registered and can see the address you tried to use, and a quick Google does seem to suggest the RFC for e-mail allows the use of the + character, but that won't matter if it's not supported by a given software. I did see a comment here that states:

For Gmail, when you create an email account, it doesn't allow you to create addresses containing a "+" sign. The "+" sign ("Plus-addressing") allows anyone with a Gmail address to add a "+" sign followed by a "string" to the end of their username to create an "alternate" ("alias") email address to use for their account. Example: "example@gmail.com", "example+tag@gmail.com". A typical (and probably "Primary") use of this is to be able to create alias email addresses for your account which allow you to tag and filter incoming email messages, theoretically filtered by sender.

which at least enlightens me as to what you were trying to do, but doesn't help beyond that.

Thank you for taking a look. Yes, that's what I like to do with Gmail.
