You could try Djigzo email encryption gateway. It's open source and 
free. Djigzo is an email encryption gateway (MTA) that encrypts and 
decrypts your incoming and outgoing email. There is a VMware virtual 
appliance available which allows you to run it without any installation 
(apart from installing the VMware image).

It currently supports two encryption standards; S/MIME and PDF 
encryption. S/MIME provides authentication, message integrity and 
non-repudiation (using X.509 certificates) and protection against 
message interception. S/MIME uses public key encryption (PKI) for 
encryption and signing. PDF encryption can be used as a lightweight 
alternative to S/MIME encryption. PDF allows you to decrypt and read 
encrypted PDF documents. PDF documents can even contain attachments 
embedded within the encrypted PDF. The password for the PDF can be 
manually set per recipient or a password can be randomly generated and 
sent to the recipient via SMS (using an external SMS gateway).
