Funny, but email validations should already just check that the address contains an @ symbol and leave it at that.

uh, nope. Email validation should check there's a valid MX record for the domain in question, and leave it at that.
Or a valid address record. Mailers fall back to 'A' records in the absence of a 'MX' record.
yes, and we could continue into checking something is actually listening for mail there, etc. But you get my point :)
