I have a strange issue with sending a mail to a maillist containing a person in another iredmail system. So I have two different iRedMail installations with different mail domains. Lets call them mail01.com and mail02.com.
On mail01.com, I have a maillist. Mainly containing users that has mail01.com addresses, and one that has mail02.com address. The strange part is that when I send a mail from a mail02.com address, to this maillist in mail01.com. I recieve an error for that particular user that has mail02.com address.
So you can send to that maillist from mail01.com without any errors. And you can also send to it from an third mailservice without any errors.
This is the error that I recieve:
This is the mail system at host mail.mail01.com.

I've tried to add the mail01.com mailserver to MYNETWORKS in /opt/iredapd/settings.py. But that didn't help. So any other ideas on how I can solve this issue?
