Hi all need some help. I have setup a iRedMail server on 192.168.0.3. I am able to get to roundcube by using 192.168.0.3/mail and can send email out to the world. But i can not receive them nor access the server from any other network joined server or external device. All ports for SMTP/IMAP/POP3 are open and directed to 192.168.0.3. I am lost and have been trying to get this working for the last few weeks.
