Well, yeah, it is technically just [email protected], I am just used to the dot :)
So, any combination of dots in there works. I have just had it since the Gmail beta. And Insert both with and without the dot as mistaken deliveries.
That's actually the likely source of the confusion, as my (example) email might be [email protected] while the serial offender is likely [email protected] (based on the salutation in the message).
