Dedicated Server/Managed Mail Server

I want a managed mail server solution that never goes down and costs very little to provision new accounts. Is there something out there that offers essentially unlimited email accounts for any number of domains, is vendor managed and NEVER goes down?

Basically I want a Dedicated Server that I would use exclusively for email. I would like to find that solution that has already engineered a great package that incorporates the SPAM filters, virus protection, web mail, etc. where I just rent the server per month. Limitations on email is just based upon the disk space I order up on the Server and bandwidth; i.e. not a fee per email account provisioned.
Do you think Greenwebpage.com servers are ok for this? Any experts' view points?
Thanks.

Happy using centoserver.com server hosting Europe. Reliability is 100% I honestly cannot remember the last downtime our site has had that wasn't because of something I did. Try this solution: HP ProLiant DL360e G8 - 2 x 10 Core Xeon E5-2470v2, RAM 32 GB DDR3, 1.92 TB (2x960 GB SSD) - $152.10/monthly.

I also got way more space and bandwidth and can say that the prices for their hosting plans are cheap.
The service is absolutely wonderful. I recommend Greenwebpage.com to all of my friends all the time.
Like their cheap ecohosting. Recommended.

Attractive deals are available from hostingsource.com and legionbox.com.

All is great with them.

A good host will get back to you with in 1 hour. If they respond quickly, is the reply friendly, does it answer all your questions and is personal? If so you can move onto the next step. Go for a medium sizes web host and I guarantee they will provide more personal help and be more willing to assist you in your needs.
