[lugm.org] duplication of topics

[Daniel Shaw]

This is interesting. I've recently re-joined LUGM, but the first few postings over the last few days have no been duplicated.

Then, shortly after reading this and thinking again "weird, I don't see this", suddenly I did get a duplicate! But it's just one post today out of quite a few.

And, what I noticed, is that the thing in common with
Apologies! I hit send instead of save. :-(

... what i noticed, is the thing in common with the example below is that is was sent by Ronny. And if I look at the headers of both I see a few other differences.

First, the initial "Recieved" header is the same:

X-Received: by 10.50.60.100 with SMTP id g4mr14863550igr.41.1442921832587; Tue, 22 Sep 2015 04:37:12 -0700 (PDT) Received: by 10.36.146.130 with HTTP; Tue, 22 Sep 2015 04:37:12 -0700 (PDT)


X-Received: by 10.50.60.100 with SMTP id g4mr14863550igr.41.1442921832587; Tue, 22 Sep 2015 04:37:12 -0700 (PDT) Received: by 10.36.146.130 with HTTP; Tue, 22 Sep 2015 04:37:12 -0700 (PDT)


But then, the next smtp "hop":

Received: by igbkq10 with SMTP id kq10so97456180igb.0 for <discuss at lugm.org>; Tue, 22 Sep 2015 04:37:13 -0700 (PDT)
Received: by igcrk20 with SMTP id rk20so78961048igc.1 for <discuss at discuss.lugm.org>; Tue, 22 Sep 2015 04:37:12 -0700 (PDT)

Different host/node ID. And also different "for" email addresses. And also different SMTP id.

I've not pasted the rest, but follow this there are differences in time stamp in all the headers. That is from this point on it's separate emails, delivered to the LUGM mailing list server separately.

It appears that this split happens before the message leaves the Gmail systems. From the first SMTP out of google-mail-something to the LUGM MX host, its already duplicated.

So. This is either an issue with Gmail generally. Or an issue with Ronny's gmail specifically.

Cheers,
Daniel

Hi,

I have the same problem as z.coldplayer. Many times I received duplicated emails from discuss at discuss.lugm.org.
I didn't bother until now. The recent email received from Ronny is duplicated, so I compared the source code side by side and here are the differences in green:
