Morning all, I hope everyone is well and I hope everyone has had a good weekend!!

Well, I'm on with a project which is to do with Roundcube and subdomains.

Does anyone know how to split down domain with roundcube ?

For example, if you had - how can I set this up in roundcube ?
I want to give each customer 5 email addresses.

I have done this before with webhosting, but I'm not webhosting I'm email hosting for customers, but would it be managed with a web control panel on my side and just set customers up as and when ?

I'm using Linux Servers - this is only a test project but something im looking to implement in the future.

Thanks all.
