Hello,
We have freshly installed iRedMail with the following setup (replaced live details with the dummy values)
iRedMail server (192.168.1.15) => added a domain "example.com" and created 2 accounts which are: test@example.com, test100@example.com.
example.com => MX record pointed to postfix proxy server (server.mailproxy.com)
In postfix:
test@example.com => pointed to iRedMail server
test100@example.com => pointed to Exchange server
Configured all the basic settings in iRedMail and postfix. Present condition is:
Sending email from "test@example.com" (iRedMail account) delivers to internal and external email accounts. The account can also receives emails just fine.
Sending email from "test100@example.com" reaches to external email accounts, but not to test@example.com. But receiving is fine.
Getting the following bounce email when sending to test@example.com:
==
Delivery has failed to these recipients or groups:
test@example.com
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.
The following organization rejected your message: 192.168.1.15.
Diagnostic information for administrators:
Generating server: server.mailproxy.com

Please not that I can send email from root@ mailproxy server to test@example.com using the mailproxy server shell without any problem.
