[asterisk-dev] Mailing List Future

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 paul at 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.
