Dear List, in order to make smtpd user auth (server-side) work postfix, I had to apply the attached patch. It makes SuSEconfig insert the option "permit_sasl_authenticated" to the line "smtpd_recipient_restrictions" in postfix' main.cf. Otherwise I got a "relaying denied" in spite of corrent SMTP authentication. What do you think? Best Regards Daniel PS.: Patch for /sbin/conf.d/SuSEconfig.postfix: # diff -u /root/SuSEconfig.postfix.original SuSEconfig.postfix --- /root/SuSEconfig.postfix.original 2003-12-01 11:11:16.000000000 +0100 +++ SuSEconfig.postfix 2003-12-01 11:13:07.000000000 +0100 @@ -335,6 +335,8 @@ postconf -c $TMPDIR -e "smtpd_sasl_auth_enable= yes" CURRENT=$(postconf -c $TMPDIR -h smtpd_client_restrictions) postconf -c $TMPDIR -e "smtpd_client_restrictions= permit_sasl_authenticated, $CURRENT" + CURRENT=$(postconf -c $TMPDIR -h smtpd_recipient_restrictions) + postconf -c $TMPDIR -e "smtpd_recipient_restrictions= permit_sasl_authenticated, $CURRENT" else postconf -c $TMPDIR -e "smtpd_sasl_auth_enable= no" fi
