Answer 1

You can use the WebConfigurationManager:

Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
MailSettingsSectionGroup mailSettings = configurationFile.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;

Response.Write(mailSettings.Smtp.Network.Host);
