Don't go that way. Rudolfo did efforts to write a nice instruction set: http://www.simpaticus.com/linux/howto/html-single/Sendmail-SMTP-AUTH-HOWTO.html Mainly all is prepared with the Sendmail which comes with Fedora to run SMTP AUTH. YOU just have to activate entries in the sendmail.mc file and regenerate the sendmail.cf from it: TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl define(`confAUTH_OPTIONS', `A')dnl --> is already active by default Then make sure saslauthd is running: chkconfig saslauthd on; service saslauthd start That is all to let mail users authenticate if they have system accounts - of course these accounts can have /bin/false as shell set so that they have no shell login. If you prefer mail users being handled independent from system users you can make use of sasldb2 or a mysql database. Another topic is the use of STARTTLS to encrypt the connections between Sendmail and mail clients so that when clients send their auth data this data is not transfered in plain text. The Fedora sendmail.mc file is prepared for this too. You only have to create a self-signed certificate with OpenSSL and let Sendmail know about it.
