Yes and no. The thing is with gnutls if the certificate is valid for another host - like I had in my test example then gnutls will not show the error and will continue as if there is no error. Obviously if the host has a certificate that is not 'valid' (e.g. self signed) mutt will prompt and ask for you to accept it first . _______________________________________________ Full-Disclosure - We believe in it.
