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.

Have you tried building the postfix SRPM from Simon Mudd's site? He has instructions on his site and it's pretty straightforward:

http://postfix.wl0.org/en/building-rpms/

I just download the latest SRPM, enable a few options and then rpmbuild a new set for my server. It's been working great for the past year.

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?

wouldn't you just rpm -e postfix then rpm -ivh oldpostfix.rpm? Although there's probably a better way.
