How to setup smtp address on virtual domains?

October 1, 2013 2.5k views
Hi, I have successfully setup iRedMail on DigitalOcean's droplet. I can also add virtual domains from iRedAdmin panel. From RoundCube, I can send and receive emails just fine. Now the problem is when I want to setup IMAP on Thunderbird. The valid smtp address seems to be the domain where I have iRedMail installed on. iRedMail was installed on a droplet with IP and DNS records for contain only A record of "mail" which point to IP I also have and which are installed on separate droplet with IP In the DNS records I added A record of "mail" which point to the mail server's IP for both and These two domains also have spf record that has text value of "v=spf1 ip4: -all" Now when I setup my email client (IMAP), I can only use as my smtp address. When I tried using and, I got errors. My guess is I need somehow map and into postfix configuration. However I'm clueless on how to do this. Is this the limitation of iRedMail community edition? If not, could you please tell me how to do this properly so I can setup my mail client with the following setup: smtp-host: user: smtp-host: user: best regards.

Seems like you still need to add some MX records.

You may also want to run your various domains through the online, Check Domain Configuration tool.
