Sorry, you misunderstood my question: Any log content in /var/log/maillog?
Also, i suggest you that, if possible, re-install your server os, then re-install iRedMail. It should be easier to fix this issue.
Please keep watching the iRedMail installation output message, paste error message here if it there's any.

This is my 2nd time installing it from fresh. The hosts uses SolusVM, so I can reinstall a fresh Unbuntu or other OS anytime. All I did before installed iRedMail was change the root password and apt-get update/upgrade. Never saw any errors during the install.
I can reinstall the VM and try on a different OS like CentOS or something if you think it would help.
It looks like their VMs come with apache installed at least because when I reinstall I get a default web page in /var/www that works.
