This post is in regards to WSS 3.0/MOSS 2007 but I’m sure the same applies in 2010.
I’m working on a project in which we’re handling responses from users via an email enabled list, that will then programmatically take action on a workflow task on behalf of the user. This is so the business users can approve/reject a given task on their mobile devices without having to be physically connected to the companies internal network.
In the email body that we’re generating for the response, we’re generating the reply to address for the email as <listalias>.<hostingserver> where listalias is the name we’ve configured on the incoming email settings for the list, and hostingserver is the host address for the SharePoint server which is handling incoming email.
String serverAddress = Microsoft.SharePoint.Administration.SPFarm.Local.Services.GetValue<Microsoft.SharePoint.Administration.SPIncomingEmailService>().ServerAddress;
but that doesn’t give you the actual name configured in the Incoming Email settings in Central Admin (Operations/Incoming e-mail settings/E-mail server display address). To get that value, you need to use ServerDisplayAddress.
Just thought I would share
