Re: Using System.Net.Mail

Hi Clark,

Could you assure that you set up the appropriate smtp server
informations in the right place inside your web.config file (i.e.
/configuration/system.net/mailSettings/smtp/network)?
A common error consists in leaving the original System.Web.Mail settings
inside the web.config file and forgetting to set up the ones needed by
the (not so) new System.Net.Mail.

Also check out [1] and [2], which have loads of information about both
the systems.

[2] http://www.systemnetmail.com/

HTH,
