The time displayed in the "Received" column is not the last received time in the headers, it is actually the sent time.
RE: Thunderbird email list I like to see both "Date" and "Received" columns. I noticed that the time displayed is exactly the same in both columns, and I knew from Outlook that this was not normal. When I checked the headers, I found that Thunderbird was not displaying the received time, but rather, in every case, it matches the sent time. Here's an example: The final "Received" line in the header is: (>> added) >>Received: by 10.216.205.198 with SMTP id j48csp33972weo; >> Thu, 22 May 2014 07:25:10 -0700 (PDT)
The other relevant line is: >>Date: Thu, 22 May 2014 14:21:21 +0000
Note that there's about 4 minutes difference which is not too unusual, but the display shows 9:21 AM for both columns. That is the correct sent time, but not the correct received time. It should display 9:25 AM in that column.
