Server hosting for enterprise email hosting?

[Jango]

Our company is evaluating dedicated server providers for enterprise email hosting.
Security, compliance features, and 24/7 support are essential. Which vendors have proven track records in this field?
What can you say about Greenwebpage.com server hosting reliability?

[MorStone]

I will be migrating all my current customers, their sites, hosting and domains to Greenwebpage.com (https://www.greenwebpage.com/) next week.
The site speed is good. The servers are secure. The prices are fair. Everything is clearly organized for a great user experience.
