Domain and get listed question?

[Magix]

Ok,

Useally i use my first domain name "pornomagix", to submit free sites, and i use an email from this domain "master @ pornomagix. com"
now i am planing to buy a new domain and to submit FS with this domain name, but i am thinking to use email from pornomagix: "master @ pornomagix. com"

So my question is: Is it Ok for link lists that i will be using email that is not on the same domain name?

and about link lists that i have accounts registeret on this email? will i have problems if i will be submiting sites with other domain ? |confused|

Thanks,
Magix
