[asterisk-dev] Mailing List Future

[asterisk at phreaknet.org]

Could you point out a specific message where this is the case?
I just looked at a few messages and I don't see bounce at groups.io anywhere.
The MAIL FROM address used in the SMTP transaction is a VERP-style 
address, unique for every recipient on a list. This way if there is a 
bounce, groups.io knows who bounced and can automatically unsubscribe 
them, without reading the bounce message at all.
Even the confirmation email I got uses a VERP-style address.

The From headers are sometimes manipulated as you may have noticed, as 
when domains are configured with a DMARC policy, groups.io will rewrite 
the From header so it still looks almost the same but is using their domain.
The old list did not do this, so to Josh's point about mailing list 
messages frequently going to spam, that may have been due to DMARC, and 
so deliverability might increase with the new list since it's handling 
it properly.

There is a List-Id header that contains the address of the mailing list. 
Perhaps you can use that in your filtering?
If you're really an ISP though, you should be allowing all groups.io 
stuff to go through since there are a huge number of other lists there.
