Thanks for taking time trying to help, Georg.  Really appreciated it.  We
have another site pointing to the same typo3 source package and email
encryption works fine there.  I suspect it might be some site specific
configuration that broke email encryption on this site.

I know regular pages have history information so you can see all the
changes that have been made on the page.  Does template record keeps
history as well?  In Tools->Log, I saw one user modified the template
record but unfortunately it just noted "Record 'Site Style'
(sys_template:1) was updated. (msg#1.2.10)" without any further details. 
I knew he was going to make a simple change (modify site title in
constants) to the template.  Other than that, I have no idea what else to
suspect.
