I have a system running GroupMail5 on Windows 7. I would like that machine to be able to connect to my iRedAdmin server and send mail. I keep getting "Client Host Rejected. Access Denied". The log file is above. How can I grant my GroupMail5 computer access to the iRedAdmin server? Is this possible?

You can try to add IP address of GroupMail5 computer in Postfix config file /etc/postfix/main.cf, in setting 'mynetworks'. For example:

mynetworks = 127.0.0.0/8 192.168.1.1

Replace '192.168.1.1' above by your real IP address. Then restart Postfix and try again.

Re: Client Host Rejected. Access Denied.

Thank you for your reply! That did work. For some reason when I use that set up to send to Gmail accounts my mail goes to spam in spite of the fact that I am using SPF and DKIM which I find to be odd. Other than that the system is working great.
