Looking at the link you mention, ssl_certificates_file is where certificates accepted by the user are saved, so pointing it at a file in /etc isn't really a good idea.
Also, it isn't anything to do with CA certificates, which is what /etc/ssl/certs/ca-certificates.crt should be (at least looking at the file name, that's what I'd expect..). If the user wants to add specific CAs to their configuration, then they can always merge them with the system CA certificate repository themselves, I guess... I have this at the end of /etc/Muttrc and it works a treat: # Include ca-certificates super-certificate set ssl_ca_certificates_file=/etc/ssl/certs/ca-certificates.crt -- Russell Howe [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
