Thank you in advance for you reading this and hoepfully helping me. Using Core 4, I am attempting the Postfix-SMTP-AUTH-TLS-Howto "how to". I've had to search for other sources (as I get this message when attempting to get anything from ftp.aet.tu-cottbus.de: Resolving ftp.aet.tu-cottbus.de... failed: Host not found.). Also, some packages are not available so I am getting the nearest source I can find. I've settled on these: wget http://www.openssl.org/source/openssl-0.9.7c.tar.gz wget --passive-ftp ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/cyrus-sasl-2.1.22.tar.gz wget --passive-ftp ftp://mirrors.loonybin.net/pub/postfix/official/postfix-2.0.20.tar.gz wget --passive-ftp ftp://mirrors.loonybin.net/pub/postfix_tls/pfixtls-0.8.18-2.1.3-0.9.7d.tar.gz Now, I've made it through the unpacking/config/make/make install for openssal and cyrus-sasl. The next part is yielding error messages: yields: What should I do?
