Important! Two domains issue

Important! Two domains issue

Hello!

My name is Pau. I had my Zoho mail running with one domain and 3 alias for the domain. And now I just purchased another domain and would like to use both.

So I would like to have domain1.com with some emails: info@domain1.com, info2@domain1.com, info3@domain1.com, info4@domain1.com

And then domain2.com with some other emails: info@domain2.com, info2@domain2.com, info3@domain3.com

I have no idea how to set up this and I'have been reading Zoho instructions and don't really get it...

Is it possible to anyone make an easy explaination please?

Thank you in advance!
