Load Signed and/or Encrypted Email and Unwrap Security Layers

See more Email Object Examples

The LoadEml method loads an email (.eml file containing the MIME of an email) and automatically unwraps the digital signature and encryption security layers. A program can then examine the properties of the email object to see what was unwrapped. AutoIt
