If You Have Problems Sending Email...

You inserted code into your application to send email, but the email doesn’t appear to work.


Step 1:  Configure your email server.  See If You Have Problems Sending Email... for details

Step 2:  Stop and restart the SMTP service in Microsoft IIS.  We've found this works in many cases!

Step 3:  Make sure your anti-virus or personal firewall software isn't blocking your email.  Typically this involves granting access to port 25.

For example, McAfee VirusScan Enterprise 8.0 VirusScan Console, Access Protection, Properties, Port-Blocking tab, Rule:"Prevent mass mailing worms from sending mail".  This blocks outbound access to any port 25 on the network.  The Edit button shows a list of excluded processes to which new processes can be added.

Add the aspnet_wp.exe process to grant permission to send emails from port 25.
