On my blog I have the notifications set to e-mail me when a post has been made/awaiting moderation.
But I get multiple (hundreds - anywhere from 15-30+ at a time) of auto-responses for the same topic in two versions: the first has the poster's user name (UserName [[email redacted]]), then a second identical e-mail from Admin (Admin [[email redacted]]).
I can delete them and there will be more the next time I check my e-mail. They'll also populate my e-mail retroactively; this morning I found some from last Wednesday, deleted them, and when I checked again they were back. I don't have this issue with any other e-mails.
We checked all of the admin settings and couldn't find anything that stuck out that could be causing it.
I'm using Outlook 2010 with a GMail account.
