David,

They do say you learn something new every day, so you have. :-)
...
Remember this is an announcement group, as that may make a difference.

Indeed. I didn't catch that.

I haven't worked with announcement groups (or at least not recently enough to remember) in either Y!Groups or Groups.io, and didn't anticipate that it would make a difference. But given your more detailed description, it apparently does.

Have you actually looked at the headers of the messages sent through
groups.io or Yahoo?

Yes, extensively. But apparently not from announcement groups.

Then at some stage, they changed the From: address to be some
convoluted version of the group e-mail address:

Yes, that's a DMARC-related change:


You may notice that Groups.io also changes From addresses, but only for certain sending domains (AOL, and Yahoo Mail among them, but not Gmail).

If there was a Reply-To: header in the message received by Groups,
that header was used instead of the above default one in the message
sent out to group members.

Interesting. I'll have to try that it my test groups (Yahoo and Groups.io). I initially thought you meant that you were using some setting within the group to apply these custom Reply-To fields. This may be the something new I learn.

I suspect this is actually a bug, and that probably the reason the
Reply-To: is being added because it is supposed to contain the address
from the incoming message's Reply-To:.

Sounds plausible.

I had thought the logic in Groups.io was to always insert a Reply-To matching the group's Reply To setting. But if that's not the case in announcement groups, and in particular if it is conditioned on the presence of an inbound Reply-To field then it seems reasonable that it should copy the field content.

I think reporting it to [email protected] would be the way to go with that.

So does that explain it enough for you? :-)

Yes, thank you!

Enough for me to want to go try it out in my test groups. Alas the work week is beginning, so I'm not sure when I'll get around to that. If you report it Mark may have it fixed before the weekend rolls around. ;-)

Shal
