I was expecting an important email. I kept checking throughout the day of Wednesday, October 27

At 10:30 pm - Wednesday, October 27, I checked again - there was nothing in the in-box. I composed and sent a reply to a previous email to the person I was expecting to hear from.

As soon as I sent it, at Wednesday, October 27, 2010 10:31 PM, an email from the person popped up in my in-box.

I looked at the short header – it indicated that it had been sent at 3:45pm that day.

I looked at the full header and found this:

Authentication-Results: SMTP; Wed, 27 Oct 2010 15:51:52 -0700

Received: (qmail 23276 invoked by uid 399); 27 Oct 2010 22:51:50 -0000 Received: from unknown 27 Oct 2010 22:51:50 –0000

This makes a twelve-hour difference between 15:51:52 –0700 22:51:50

What happened? Did my email reply at 10:31 trigger an automatic response initiated by reception my reply?
