yes, but DONT DO THAT unless you know what you're doing. you have been warned: smtpd is safe by default and provide a SSL_CIPHERS that has been tested and verified to be safe. changes that seem fine can effectively break the security and interoperability. unless you know how openssl/libressl manag

I think at build time you can fine-tune which ciphers you want by editing ssl.h -- in particular the SSL_CIPHERS define. --Adam On Mon, 9 Jun 2014, Gilles Chehade wrote: > On Mon, Jun 09, 2014 at 08:39:52AM +0100, John Cox wrote: > > Hi > > > > >>That's not correct no, I get plenty of TLS 1.0 t
