adding email addresses with different domain

adding email addresses with different domain

hi
i have all my incoming email to:
info@1st-website.com

having set up a 2nd website i now want to use the same mailbox to handle the mail to and from:
sales@2nd-website.com

i am in the process of getting my MX records for 2nd website to point at zoho
(have to wait a bit for my hosting company, but thats ok)

just want to know what i will have to do at this end

is it as simple as buying a 2nd user account?

ta
Dave
