Estoy intentando hacer autentificacion SMTP en SuSE 8. bein estoy intentando segui la doc pero me encuenttro con un problema: cuando en la doc de sendmail (http://www.sendmail.org/~ca/email/auth.html) pone: Next, create a configuration file called Sendmail.conf if needed/wanted. Create a sasldb password file using saslpasswd if you use any mechanism (CRAM-MD5, DIGEST-MD5, PLAIN if pwcheck_method: sasldb is used in the .conf file) that requires it. BTW: sendmail requires sasldb to be owned by root or the trusted user and not be readable by anyone else since the file contains sensitive data (shared secrets). If there is a conflict with other applications that need to read it too, you can try a trick. No esta nada claro, ademas a la hora de crear el archivo pone: By default, the Cyrus SASL library reads it's options from /usr/lib/sasl/App.conf (where "App" is the application defined name of the application). For instance, Sendmail reads it's configuration from "/usr/lib/sasl/Sendmail.conf" and the sample server application included with the library looks in "/usr/lib/sasl/sample.conf". A standard Cyrus SASL configuration file looks like: srvtab: /var/app/srvtab pwcheck_method: kerberos_v4 no hay fichero srvtab. tambien en la doc pone: APPENDDEF(`confINCDIRS', `-I/PATH/TO/SASL/include') donde esta el include de sasl en SuSE 8?? Bien si le queiro una autentificacion plain o contra el nombre usuarios del ordenador. Tengo que crear algun archivo con algun formato en concreto? muchas gracias y espero vuestra ayuda.
