Just remember that GCE does not allow outgoing mail on standard ports such as port 25 or 587.
You must route through a mail relay service such as Sendgrid for all outgoing mail unless you use googles own paid gmail.
Essentially,
You send all outgoing mailon non standard port to Sendgrid, who then relay it to recipients on standard ports so the mail can be received.
Hi Malc, and thank you for your answer. From what I understand I have to set A and MX records for all the domains with my registrar and point them all to the same IP which will be the IP of my VPS.
That sounds to easy. Do I have to do any other specific changes in Virtualmin for all the domains?
Also you say you use Cloudflare for DNS - do I set this through Virtualmin or again with the domains registrar?
Thank you for taking the time to answer!
You can't avoid DNS setup. You have to do DNS setup for your website to work. For that you have an A record that says, for example mydomain.com is 123.456.789.012. For mail all you have to do is add an MX record saying mail.mydomain.com is your mail server. Usually the website where you set up your dns will walk you through it. Once that is setup so that mail goes to your IP address (same for hub and all your domains) then webmin/virtualmin handles it ending up in the right mailbox.
Hello. First of all great article and so easy to follow. I am coming through the same thing as you - trying to get rid of the shared hosting and go the VPS route. What I struggle is the mail setup. Now I have similar configuration to yours - 1 "hub" domain as you call it and 3 separate websites. I don't want to setup DNS, but I am not sure what to write as a DNS entries for the mail to work. Basically will you be able to share the steps for the mail setup and how to route it for the 3 different domains? Or at least some guidance will be great and much appreciated. Thank you in advance.

The validation tool from appmaildev.com is not on their website anymore. I have found a new one at https://www.emailtooler.com/authentication-validator/. It works exactly the same and is great!
