Hi list, by now i found out how to set this up, after spending 3 days of research (i am sorta new to this :) ) Here the link that runs you through the setup of Sendmail >=8.10 using cyrus-sasl to enable sendmail authentication. also i am wondering about your oppinion. Is this a good solution, is it a hack, what do you think http://www.ledge.co.za/scripts.phtml?page=smtpauth My configuration SuSE 7.3 cyrus-sasl-1.5.24-157 openssl-0.9.6b-62 sendmail-tls-8.11.6-82 btw, if someone could mail me the syntax for the following solution smtp over ssl, while running sendmail as independant deamon. probabbly someting like smtps stream tcp nowait root /usr/sbin/stunnel smtp -p /usr/local/ssl/certs/mail.pem -r smtp thanks for yer help, most of my answers i found in the archives here. regards and good nite Evert
