If you need plain old Postfix, you just aptitude install postfix.
If you need LDAP support in your Postfix instance, you just aptitude install postfix-ldap.
Is it really that hard?
And regarding OpenSSL, the problem is not in Debian. Just check http://people.gnome.org/~markmc/openssl-and-the-gpl.html
OpenSSL always had a problematic license.
With respect to the OpenSSL stuff, I'm not talking about the GPL license - I'm talking about http://www.debian.org/security/2008/dsa-1571, one of the most painful security issues in recent memory and caused by a meddling maintainer. (Certainly, the upstream team could have more clearly warned him, but without the maintainers changes everything would have worked just fine.)
I understand you spend a lot of your free time working for free, and I appreciate your good intentions and the good that Debian and Debian's developers have done (e.g. writing lots of man pages for programs that have none) - but I do think Debian has some really questionable sides as well.
But why does Debian split up Postfix (well-written, actively maintained) into a zillion different packages stitched together by dynamic loading, instead of just configuring it properly? Why does Debian fuck up OpenSSL?
