Dear List I am using dovecot sasl with postfix smtp-auth. I also use tls with both dovecot imap/pop server to retrieve mails and also tls with postfix for submission to the relay server.
With dovecot I can have my mail client send a certificate and make dovecote use CN field of the cert as username to authenticate. If I enable that feature in dovecot, postfix authentication does not work despite the fact that I am also sending the same cert to postfix. I wonder if there is a way to do that and I don't know how. Also if I enable the feature "require client cert" with dovecot server then postfix auth again does not work. Is that because dovecot socket is not accepting cert information or postfix is not sending the information? Any way to make it work? What if I go with a cyrus sasl? Any explanation on these issues will be appreciated. Thanks mr.wu.
