The mailing list for listmasters using Sympa

[Tom Fillmore <address@concealed>]

Hi, all -

Thanks for the replies on this.  Roel, I tried what worked for you and it did not work for me.  Bummer, that would have been great.  Erik, your description is spot-on although in my case it doesn't matter which view (thread or otherwise) is enabled.

So it appears that the solution here is to rewrite headers on the outbound to remove Gmails' ID information.  Ooof.  I don't believe Sympa has a way to do that cleanly, but of course it is possible via other means.

I'm thinking someone has already tackled this rewrite problem - if you have can you please respond with how you did it?  If no one responds I'll take a look at it and post results but I won't have time in the next couple weeks.

Thanks everyone, it's great to have a community to fall back on.

I hope you are all safe and well.  :)

Our list has had similar issues.  Gmail implements a de-duplication algorithm based on the message ID, so when the e-mail comes back from the list, it is silently discarded.  There appears to be no setting to override this.

Interestingly, our users only perceive this as a problem when they are originating their own conversation with no replies from others.  The reason is that most folks are seeing "thread view", which mixes their Sent mail in with the received mail but only when there is received mail for that thread.  So as soon as there is another's e-mail from the list, they suddenly see "their post" as well.  It doesn't matter to the user that it's their outbound copy, their perception is "my post went through".

And yes, this problem goes away when rewriting the message in any way that the original message-ID and such are changed.  But that's a big ask in 2021.

Hi Tom,

I had a similar problem. After reading about it, it seemed the proper solution was to implement/configure ARC, but I didn't manage to do so properly, so in the end I configured the "New From name format" setting in the DKIM/DMARC/ARC section to "List", and after that we had no more missed emails. Not ideal, but it worked.

YMMV, maybe your issue is something completely different.

Best regards,

Roel

Hi, all -

I'm struggling with this one...

Some list members with gmail addresses experience the problem of mails they send to a list from gmail are not showing in their gmail inbox after distribution back through the list. Not all gmail users experience this problem.

Example:

A subscriber sends an email to a list from gmail

It is accepted and passed back through the list to that person with a 250 code from gmail (confirmed by reviewing mail logs)

The email they sent is in their sent folder

The email sent back from the list to the subscriber does not show up anywhere in gmail, including trash and spam.

To me this suggests a gmail setting but I can't find anything that would do this.

Any help would really be appreciated.

Thanks!
