I am new to hMailServer and am just about to install it on a server running Windows Server 2008 R2 Web edition.

As well as normal email accounts, I have an ASP.NET web application that uses .NET mail and an SQL Server 2008 database that uses SQL Server Database mail.

My question is: I gather that hMailServer has its own SMTP server. Will this suffice for the .NET mail and SQL database mail, or do I need to install the Microsoft SMPT server and use it for these purposes?

Thank you for any assistance.

Depends on how you set them up.

In default situations I believe that both use the drop folder method, which hMailserver does not do.
Normally to use .NET mail I extend the .Net Mail with the relevant Microsoft SMTP Schema http://msdn.microsoft.com/en-us/library ... 10%29.aspx

I expect that the SQL Database mail is the same, though I've not used it

I can report that there was no problem using .NET and database mail using the hMailServer SMTP server with Windows Server 2008 R2 Web edition, ASP.NET 4 and SQL Server 2008 R2 Web edition.
