Hello,

It was suggested that we should look at the mail headers when the mails arrived in a strange order. Here is an example:

========= Mail 1:
Delivered-To: (...)@gmail.com
Received: by 10.140.91.161 with SMTP id z30csp56304qgd; Tue, 25 Feb 2014 02:00:33 -0800 (PST)
X-Received: by 10.180.98.71 with SMTP id eg7mr1384013wib.31.1393317956616; Tue, 25 Feb 2014 00:45:56 -0800 (PST)
Return-Path:
Received: from freepascal.dfmk.hu (freepascal.dfmk.hu. [193.224.143.39]) by mx.google.com with ESMTP id
fy2si7547187wib.56.2014.02.25.00.45.55

        for <multiple recipients>;
        Tue, 25 Feb 2014 00:45:56 -0800 (PST)

========= Mail 2:
Delivered-To: (...)@gmail.com
Received: by 10.140.91.161 with SMTP id z30csp61355qgd; Tue, 25 Feb 2014 03:23:41 -0800 (PST)
X-Received: by 10.15.74.130 with SMTP id j2mr5523eey.116.1393316139032; Tue, 25 Feb 2014 00:15:39 -0800 (PST)
Return-Path:
Received: from freepascal.dfmk.hu (freepascal.dfmk.hu. [193.224.143.39]) by mx.google.com with ESMTP id
a41si41401169eef.71.2014.02.25.00.15.36

        for <multiple recipients>;
        Tue, 25 Feb 2014 00:15:39 -0800 (PST)

I only copied the first headers because I believe they are enough to get an idea of what is going on. IIUC, this is happening inside Google's systems. Am I correct? If so, I should probably ask Google what is going on. I know: I don't have much chances of getting an answer.

BTW, I don't know what the X-Received header means.

It means the mail was received by mx.google.com and then delayed by 1:15h by Google's internal servers (10.* is intranet).

Same here. This time Google delayed it more than 3h.

Yes, according to their own log entries.

If so, I should probably ask Google what is going on. I know: I don't have much chances of getting an answer. BTW, I don't know what the X-Received header means.

I asked and I got an answer from Google, they were having issues with their servers. No information about what issues, though. And no explanation as to why this only happens to these lists (from all the MLs which land into my GMail box)

I'll try again next time I spot a discrepancy. In a few tries, I feel I'll be in a position to ask an explanation for this "coincidence".
