Trying to test Blogengine.net... I was able to set the blog and it works. However when I try to test email (registered with Google apps) I receive following error: Could not connect - Request for the permission of type 'System.Net.Mail.SmtpPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. smtp.gmail.com is on 587 port - could it be an issue?
Just would like to add that the same blog with the same setting works fine on mine home computer - it send emails.
Try increasing the trust mode on the application to a higher level. http://support.Winhost.com/KB/a657/changing-the-default-aspnet-trust-level.aspx
