I'm trying to setup my email server using this guide: http://www.howtoforge.com/virtual_postfix_mysql_quota_courier I already have my debian setup with the following repository sites in my /etc/apt/sources.list file: deb http://mirrors.usc.edu/pub/linux/distributions/debian stable main deb-src http://mirrors.usc.edu/pub/linux/distributions/debian stable main deb http://security.debian.org/ stable/updates main I also searched in the forums to find that someone else could not find the libsas12 package as well and someone suggested to change the sources to the following server: deb http://ftp2.de.debian.org/ stable main deb-src http://ftp2.de.debian.org/ stable main I changed them and did an apt-get update and tried to do the first section of the guide (installing postfix, courier, saslauthd, mySQL and phpmyadmin). Anyone know which servers have this package? Also, the guide might need to be updated, since I followed the instructions and it doesn't seem to find the required packages to use the guide. Has this package been taken out of the repositories? Thanks.
