SMTP client timeout issue with addresses that include an underscore.

I am using system.net.mail to send out notifications for signups. my problem is that it works just fine unless any of the email addressess entered have an underscore.

will timeout. Does anyone know what might be causing this.

it shouldnt. I've done it and works fine over here. I would suggest, as silly as it sounds, to disable your anti virus software and see how that goes. If you can, try to increase the timeout limit as well of the smtp client object to double the time and see if it still times out.
