[stunnel-users] SSLv3 not working with version 5.06

Maybe Debian removed support for SSLv3 in it's OpenSSL libraries. This protocol is now obsolete and should not be used. 
Is that is the case, you will need to compile your own OpenSSL with SSLv3 enabled. 

Anyway, you should ask in a Debian forum.

Jose
