[Mailman-Users] how to avoid the anit-spoofing error

[Weijun Zhu]

Hello,

I am running a list where a few subcribers are from a company. The list 
server is outside the company.
Everything works great!
But it seems that this company recently implemented anti-spoofing on 
emails and subsribers from that company
are no longer able to receive any emails sent to the list by people from 
the same company. Here is the log message I got.

 (reason: 550 Error: Anti-spoofing - From header field in inbound eMail cannot be local domain)


Is there a way to configure the list server so that this problem can be 
avoided?

Thanks a lot!
Weijun.
