Looks like this old Yahoo email address is spamming an email with what I am sure is a bad link. I cleared this email a long time ago and it looks like it is mailing a lot of non-valid email address which are bouncing back. I can't do anything about it ATM because my PC is in the middle of getting its hard drive replaced.
Very sorry about this. No idea how this can happen as I don't even log into this account except via my iPhone. If you got the email and clicked the link, fire up those virus checkers.
