hi Crimson thank you for the reply.
i currently have the domain hosted on mydomain.com for the dns etc. so what i was wondering is if i would be able to signup here and put a main domain on there, which is np at all, then this second domain i have currently on mydomain.com for the dns to change the pointer there for the MX to point to my dreamhost account for the MX for that domain, and still leave the domain hosted on mydomain.com.
anyone know if this cna be achieved? or is there a way i can maybe move the domain to dreamhost and then have the MX here and then redirrect the domain to another A record host.
