Hello guys, I have a client that is insistent on retaining their current email application, SmarterMail, but the problem is the application requirements: SmarterMail was desgined to coexist with multiple applications on the same server based on the following minimum requirements: Windows XP*, Windows Vista*, Windows Server 2003 or higher SmarterMail Web server included with product Microsoft .NET 4.0 Framework However, SmarterTools recommends the following requirements for maximum efficiency: Windows Server 2003 or higher Microsoft IIS 7.0** Microsoft .NET 4.0 Framework I know your servers run on non Windows based OS's, I am reluctant to switch or find an alternative provider as I have dealt with a number of hosts and I am really happy with your service. Please do let me know, or of my possible alternatives. Any help is much appreciated. Thank you.
