TIS/PEM <-> MIME Info Wanted

The company I work for makes a MIME-compliant mail user agent which runs
on almost all UNIX systems and is close to being commercially released
on the Mac and MS Windows platforms. I have been getting a lot of enquiries
lately from customers and prospects regarding how to implement encryption
in their e-mail.

I have gotten a copy of the TIS/PEM FAQ and have read through it, but would
appreciate it if you'd send me any new info you have regarding PEM/MIME and
how I might go about implementing it into the Z-Mail MUA.

Thanks in advance for any help! ;)
