Question

How to setup smtp address on virtual domains?

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 1.2.3.4 and mail.domain1.com. DNS records for domain1.com contain only A record of “mail” which point to IP 1.2.3.4

I also have domain2.com and domain3.com which are installed on separate droplet with IP 5.6.7.8. In the DNS records I added A record of “mail” which point to the mail server’s IP 1.2.3.4 for both domain2.com and domain3.com. These two domains also have spf record that has text value of “v=spf1 ip4:1.2.3.4 -all”

Now when I setup my email client (IMAP), I can only use mail.domain1.com as my smtp address. When I tried using mail.domain2.com and mail.domain3.com, I got errors. My guess is I need somehow map mail.domain2.com and mail.domain3.com 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: mail.domain2.com user: user@domain2.com

smtp-host: mail.domain3.com user: user@domain3.com

best regards.

Seems like you still need to add some <code>MX records</code>. <br> <br>You may also want to run your various domains through the online, <a href=“http://www.webdnstools.com/dnstools/domain_check”>Check Domain Configuration</a> tool.
