The SMTPClient component from Bossware is a .NET SMTP client that allows developers to implement outgoing email functions for their email applications and Web pages. It does not use the .NET Framework's System.Web.Mail namespace, which is merely a wrapper for CDONTS and CDOSYS, and which is reputed to be resource-hungry and to behave differently depending on the OS of the computer. The component is written in 100% managed C# and is CLS compliant.
