IredMail working just fine, we getting all emails in/out but i have another email server for system alerts which other servers connects to via smtp
this is how i have it set and works just fine before until we switch from exchange to ired
1. IredMail Server Domain: domain.com
2. 2nd email Server Domain: e.domain.com
Both servers are using internal IP's, but Ired server has a NAT static ip and other email server does not is only for internal use
NOTE: in Ired, i edit file /etc/postfix/main.cf and added my local ip x.x.x.x/24 and still does not receive email from 2nd mailer server.
any help will be great
