Depending on the client, the default security may be something other 
than PGP. Thunderbird comes to mind. I think it uses SSL. Gmail uses 
TLS. Yahoo! uses DKIM. Not that PGP can't be added as a plug-in or 
extension, sometimes (e.g. Thunderbird), but that may be beyond the 
capability (and willingness) of many people.

I'd love to encrypt some of my email, but haven't been able to get 
agreement from even my most savvy acquaintances.

Let us know how it goes if you decide to tackle it.

Email from the library showing overdues, or holds might be sensitive. Would it be possible for our email systems to ask for a public PGP key along with email and then use that whenever sending out notices? Should my hospital, insurance company, bank, and so on be doing the same? Just asking, maybe we could take the lead on privacy in this area.
