Send S/MIME Signed Email

Send digitally signed email using the digital certificate of the recipient. To successfully sign, the sender's certificate must be pre-installed with private key. Typically, this is done via a .pfx file, or through Internet Explorer. If your code is going to run within ASP, ASP.NET, or a Windows Service, you will need to follow the instructions here (http://blog.chilkatsoft.com/?p=149) to import your certificate w/ private key such that it is accessible by the calling process.

# (with private key) in the current user's personal certificate store.

# matching the sender's email address.  Chilkat searches
# the Current User's Personal certificate store, as well
# as the Local Machine's Personal certificate store.
# Run certmgr.msc to view the certs in the Current User's
# certificate store.
