again just trying to help
when i signed up for the new mailing list
see headers below,
a few things to note, return address & from address needs to match, this
is a common spam filter which is enabled on my email server.
You have no idea how many emails come in saying from "Paul Kudla
<groups.io>" for example which my server picks up as a bad email address
before delivery. (Because Paul Kudla is p...@scom.ca ?)
Reply-to carries the same issues which is why they are ignored coming
through the system.
on other notes postfix is programmed for FQDN and reverse ip looks etc
that must match the sending smtp serve sending the emails. Sincce stuff
is showing up that does not appear to be an issue but thought i should
mention that.
also note i and no one else opens an entire domain like groups.io or any
other domain(s)
it would be like allowing all email from *@gmail.com
just not practical.
scom.ca is a small provider compared to others but over 80% of my email
server traffic is spam, hacks etc and programming is in place to prevent
anything from wrecking a customers account (viruses, blacklisted ip's
etc) - this is what prompted the SPAMCOP.NET issue as it is one for the
dnsbl lookups on my postfix server. I had access to the log files so was
able to track that down, but another question it seems if email bounces
back to groups.io do you get a report ? - a lot of email servers like
microsoft do not report bouncebacks thus making it hard to trace issues
upon setup.
I know you are restricted by the groups.io and apparently this is a free
account, which is why i suggested if groups.io can interface to an
external email server or at least an external out smtp server that is
programmed with all the correct setups (spf,dkim,ssl etc etc)
it seems you need to be in more control of the outbound email side.
inbound emails could still be received by the groups.io server on the mx
record side ?
just a thought out load as I am not fimiliar with groups.io setup up
until now. It seems a lot of assumptions are being made (aka willy nilly
sending emails without proper formats?) because groups.io is doing
things on your behalf.

Could you point out a specific message where this is the case?
I just looked at a few messages and I don't see bou...@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.

Good morning
I got verified however the new mailing list is using
Asterisk Development Team via groups.io <bou...@groups.io>
note the bou...@groups.io
should really be an asterisk email address
if i open up groups.io (like msvc etc) then spam will flow
i am an isp and apologise for the comments knowing you are doing you
best, just letting you know some difficulties before they become a
large scale issue
Have A Happy Thursday !!!

I did get the signup and also set my password but am unable to
proceed.
SPAMCOP.NET <http://SPAMCOP.NET> is super flexible (ie will track
and update bad ip's on the
fly within 24 hours, so to land on this list means a server has
been
very very bad.
let me know if i can help further.
I don't think either of us can really help. Looking at groups.io
<http://groups.io> posts this appears to happen sometimes, be it as
a remaining result of a Yahoo migration that occurred in the past or
from group admins adding email addresses for SpamCop spam traps in
some capacity.
InterLinked: You previously stated that most lists you've been on
migrated to groups.io <http://groups.io>, has this been a problem
for them and if so how did they approach it (if at all)?
I have to be on at least 2 or 3 dozen groups.io lists at this point
and I've not really seen this be much of a problem. It haven't seen
it on any of my lists with 100+ members or really heard about it on
other lists. Occasionally, maybe a couple times a year, there are
*bounces* and I know groups.io will auto unsubscribe users if it gets
bounces to comply with email subscription policies and what not. I
don't have any specific experience with SpamCop, that isn't a service
I use on my mail servers.
I think this is going to be inevitable to some extent with any hosted
mailing list. groups.io has a pool of IPs that they use but obviously
they are shared between lists. Digium has been self-hosting lists so
it hasn't had to worry about this in the past.
groups.io also has an online portal where you can register and manage
groups, but that probably entails receiving an email at some point so
you might run into the same issue there if you can't receive email.
Can you add the sender to your "safe senders" lists? IMO email
services that don't allow the spam rules to be overridden are
fundamentally flawed, but I realize you may not have control over
that or be able to switch services.
It probably doesn't hurt to get in touch with the guy that runs
groups.io, here: https://groups.io/helpcenter. I and others have
reached out before for things and he's helpful and responsive.
