I've been looking through several howto's and also the sendmail (on the system and the website) docs, but I've now come to a halt. I'm trying to get sendmail to only allow sending of mail, providing the user can authentication. I have set the following options up in my /etc/sendmail.sendmail.mc file and ran the m4 update to update sendmail.cf: define(`confAUTH_OPTIONS', `A')dnl TRUST_AUTH_MECH(`LOGIN PLAIN DIGEST-MD5 CRAM-MD5')dnl define(`confAUTH_MECHANISMS', `LOGIN PLAIN DIGEST-MD5 CRAM-MD5')dnl define(`confCACERT_PATH',`/usr/share/ssl/certs') define(`confCACERT',`/usr/share/ssl/certs/ca-bundle.crt') define(`confSERVER_CERT',`/usr/share/ssl/certs/sendmail.pem') define(`confSERVER_KEY',`/usr/share/ssl/certs/sendmail.pem') But when ever I telnet in or use evolution to get the available authentication methods (I'm trying to use Plain or Login, as I have STARTTLS enabled anyway), I only get the following options: 250-AUTH DIGEST-MD5 CRAM-MD5 checking /var/log/maillog, its listed as: sendmail[10740]: AUTH: available mech=DIGEST-MD5 CRAM-MD5 ANONYMOUS, allowed mech=LOGIN PLAIN DIGEST-MD5 CRAM-MD5 I can see that it knows of the methods, but for the life of me I cannot workout how to make it available, I presume it has something to do with the 'confAUTH_OPTIONS' directive, but the readme in the sendmail.cf directory, says to read a non existent file. Can someone advise my on what options I'm missing or need to add.
