Email on forwarded domains

I don't know if this is the correct forum to post this question, please let me know where it belongs if this is in error. Also, this is probably a simple question but I just don't know the answer.

I have a client with a main domain that he uses to represent his business. He has somewhere around 10 other domains he wants us to host, but he just wants them to forward to his main domain. He does want to have various email addresses at those other domains though.

Will there be any problem receiving email at those domains due to the forwarding of the web stuff? Any input on this would be greatly appreciated.

No problem with that at all

As you create domains in Panel they immediately have mail ability for domain.com. It's not a requirement from the mail perspective that the domain actually host physical files.

Sorry for my lack of courtesy, I've been away for a few days. I appreciate your response and the client will be very pleased about this too.
