hi all, i tried to install postgrey for postfix and had to update postfix to version 2.1. i added the following to /etc/yum.conf [postfix-2.1-rhel3] name=Postfix Mail Server for RedHat Enterprise Linux 3.0 - $basearch baseurl=http://ftp.WL0.org/yum/postfix/2.1/rhel3/ after the update i have problems because the new version of postfix doesn´t support SASL. is there an postfix-tls rpm for CentOS 3? If not how can i remove postfix 2.1 and install the old version with TLS support? thank you very much for your help
