Unfortunately ClearOS does not support multiple virtual domains and you've done better than me by finding the document I was looking for! The only way is multiple instances of ClearOS in VM's. It can have a single ClearOS gateway as ClearOS supports mail forwarding to multiple servers.

Multiple email domain

Hi All,

AS Google announced the end of historical G Suite, I get hi-jacked by this F..... Google and I need to store distinct account on distincts mailbox.
I hope that emailalias might solve this but it seams not supported by design : Does ClearOS Support Multiple Virtual Mail Domains?

Solution have been explored here : Multiple Semi-virtual Mail Domains!
I need to manage at least 3 to 12 domains, no commun mail box.
I've got around 50 mailboxes at all
I need secured and authenticated connection throught POP and SMTP.

My urgent action is to substitute My G Suite account with Gmail account by masking this gmail acocunt and keeping using the original domain email addresse.

Any suggestion or help to do this on a unique clearos instance is welcome. Event if manual configuration is required

Thanks in advance
Help me, Obi Wan Kenobi. You're my only hope.
