There are several ways you can do this. You can:
1) use MAPI or Automation to control the mail client on the PC.
2) use a third party product like IDS Mail (www.intuitive-data.com) or Mail Manager (www.classycomponents.com) that will do the interface to the mail client for you.
3) Use Rick Strahl's ipstuff (www.west-wind.com)
