I tried to replace the POP3 and SMTP settings using anyone of those two IP addresses but that didn't work. Other things I did which didn't help include:ġ) checked the virtualBox settings -> Network -> Host-only Networks and I get these infor However, when I tried to create a new user account using Thunderbird from the host, I received "Thunderbird failed to find the seetings for your email account" error message. I have also use Thunderbird email client on the guest and it was fine. I have tested the iRedMail installation and it was definately good and I could create two dummy user accounts and they can sent to each other. It also has the same Ubuntu 12.04.2 LTS OS as the host machine. I tried to send email using thunderbird email client from a host to guest but failed.
