I have an online form that deliver email to my gmail account. it had been appearing to work normally for a long time, years, until 6 Sep 2011 when suddenly 250+ emails arrived in my inbox at one go. But looking at the header, these were sent between June and August. Can anyone decipher from the header what happened? Otherwise what mechanism might have cause this?
