I am running MM3 and have a list that has users from different organizations and email domains.
So let's say I am orga.com and hosting mailman Bill is borg.com Cindy is mew.com
When Bill sends a message to my MM3 list it gets sent out, However, cindy's email system rejects it cause it sees the message is sent from Bill@borg.com but it came from my MM3 server which is under orga.com, so it rejects it.
I have been told more organizations are checking this and starting to reject these types of messages and also we could get blacklisted because it looks like we are spoofing.
The only solutions I can think of are:
-Have the receiving organizations whitelist my server, but that is probably not feasible. -set the list to anonymous..... But then you don't know who sent the email.
Anyway around this? or is there a way to have the sender's email included in the list message but keep the list anonymous?
or am I missing something else?
and if I send amessage from my organaxztion to MM# it will go out to the peopl n the list, and if and some of those people are at other organizations. When the recive the email, sometoimes their mail system reject it with a DMAR message. I have been told thisis beacue the other organazatione dmeail system sees I snet the message
