How to pass authentication credentials in System.Web.Mail class
I believe this is a FAQ on the ASP.NET Forum and other newsgroup as well, and the answers/replies are normally be - “No, you can't! You have to use other third party control in order to do so if your mail server require you to logon.“
This's not always true... and I learn something new from Mike (more info can be found at my previous blog - FAQ for Email Sending in ASP.NET) today, he show us how to write 3 lines of code so as to send a authentication required MailMessage object in ASP.NET.
Awesome!
