The value of this setting tells AuctionWorx where to direct all outbound email. The server defined here should have relay permissions enabled so that emails can be sent out to third party domains.
Set this value to an email server prepared to accept SMTP email and relay it to its final destination.
To set your email server, you would change the highlighted value below
<network host="yoursmtpserver" userName="username" password="secret" port="25"/>
