I am attempting to set up smtp auth on a centos 4.3 box. Currently sendmail-8.13.1-3.2.el4.rpm is installed. I want to upgrade to 8.14, which has built in cyrus-sasl support. I attempted a rebuild of a src.rpm to do this, but it complained about a number of different dependencies. I am not finding any docs on how to successfully get to 8.14 on this distro, so am about ready to install from source. Of course there are a number of dependencies: error: Failed dependencies: /usr/sbin/sendmail is needed by (installed) redhat-lsb-3.0-8.EL.i386 /usr/sbin/sendmail is needed by (installed) squirrelmail-1.4.8-4.0.1.el4.centos.noarch smtpdaemon is needed by (installed) mdadm-1.12.0-2.i386 smtpdaemon is needed by (installed) mutt-1.4.1-12.0.3.el4.i386 smtpdaemon is needed by (installed) fetchmail-6.2.5-6.0.1.el4.i386 sendmail is needed by (installed) rt-mail-dispatcher-3.4.5-2.noarch Will the dependencies work again with the new, source 8.14 install?
