There are two main examples: - I use first.last and get email for firstlast - I use <initial>last and get email for <initial>.last Then there are some really weird ones where the dot is just _randomly_ added or moved around, or where I get e-mails with multiple dots in the middle of the address (a.b.cde), etc. None of these would be accepted by a normal e-mail service unless there was a _real_ matching mailbox or alias. And this does not happen on a single mailbox, nor targeted at a specific alias. Sometimes it's as if someone were shotgunning various combinations, and I have no clue how some of those e-mails are considered valid by the senders, since _I think_ all the validation codes come into my inboxes. This also raises some questions as to whether mail addressed to me actually makes it to its destination...
