Domain email settings - can things be in conflict

Domain email settings - can things be in conflict

Currently I have a domain name that I have hosted at a photography site (Smugmug).   At my domain registrar I had to enter stuff so that my domain is correctly pointed to the photography site (Smugmug).   At the photography site they do not handle the email side of things.   Is it possible for Zoho to handle all the email / calendar / contacts side of things and yet keep my photography site intact and working.

Cheers,

Steven Taylor
