Business Email Service

Small Business email service vendors for individual's domain?

Please suggest some nice(service/features/price) email service vendors where can receive incoming mail for my domain (Small business - 10 email addresses or so) & can use pop kind of service to use it integrated with MS Outlook.

1. I use Mozilla Thunderbird... I definitely rather it than MS Outlook. I use it for 5 of my Yahoo Small Business e-mail accounts.
