Having a separate email account for your Linux hosting makes everything much easier to organize. You wont have to sort all your online correspondence with other matters in your main personal email. You client related concerns and other communications relating to the site youre hosting can go into the email that comes with your web hosting package.

Make sure that when you sign up with a web hosting site that you get a virtually unlimited email account supply. Theres no point in going for a web hosting site that offers limited email accounts when you could go for one that gives you more. It will allow you to further segregate your email using multiple accounts as well as provide accounts for every other domain that you have.

Of course, there are a lot of web hosting sites that offer this alongside linux hosting. Not only do you save because youre using an open source operating system, but you also save because you have unlimited emails.
