I am moving my project from windows 2003 to windows 2008 server.i configured SMTP similar to 2003 in 2008.Iwhen i am sending the mail from web it is going to Bad mail.When i am sending the mail form SQL notification services i am getting the below message "Mailbox unavailable.The server response was: 5.7.1 Client does not have permissions to send as this sender"

this behavior might occur die to relay restrictions http://www.howtogeek.com/howto/database/sending-automated-job-email-notifications-in-sql-server-with-smtp/ http://mscerts.programming4.us/windows_server/Windows%20Server%202008%20%20%20Configuring%20SMTP%20%28part%203%29%20-%20Configuring%20General%20SMTP%20Server%20Settings.aspxhttp://www.virmansec.com/blogs/skhairuddin

I need to send email from SQL server Notification services not from the SQL job
