since the year dot.  I don't think it's totally unreasonable to  
refuse opportunistic encryption from people using self-signed  
certificates: to the eyes of the uninitiated SSL in that situation  
appears to offer authentication when in fact it only offers some  
measure of confidentiality.

My memory is that it wouldn't accept my signed-by-a-self-signed-CA  
certificates, unlike IanM's experience, but it was a long time ago  
that I bumped into this problem.
