Hi Evan,
Do you mean you are using System.Web.Mail to send the smtp email?
From the MSDN we know that
The System.Web.Mail namespace contains classes that enable you to construct
and send messages using the CDOSYS (Collaboration Data Objects for Windows
2000) message component. The mail message is delivered either through the
SMTP mail service built into Microsoft Windows 2000 or through an arbitrary
SMTP server. The classes in this namespace can be used from ASP.NET or from
any managed application.
While the CDOSYS did not shipped with windows 98.

Also you may try to read the related google thread for your reference.
