Password protected e-mails

You could use OLE to integrate SAP with Excel - create files, execute macros etc. (search for DOI on SAP help), but this will only work on the presentation server, so you couldn't run it as a service in background. I suppose your e-mails are sent through the internet, hence the requirement for encryption -- or maybe your client doesn't trust its network people! For this you really should use strong encryption -- anything less, you might as well send plain text. One solution to this would be to send the email down a VPDN -- this would encrypt all traffic between source and destination. Another would be to encrypt the file just before it is attached to the email. This could be done within ABAP, but perhaps a third party public key encryptor would be better placed. This could be invoked via a system command call, or as an RFC. A third solution would be to have your mail server handle the encryption.
