[OpenIndiana-discuss] Qmail-to-go on openindiana?

[Gary Gendel]

With all this discussion about Postfix vs. Qmail, I started looking at 
what it would take to replace my Qmail installation with Postfix.  I 
started looking at what it would take to replace spamdyke with postfix 
functionality.  Most things have a direct correlation.  One case so far, 
greylisting, requires running an independent email proxy for postfix 
where it is incorporated in spamdyke.  I'm still working through the 
list but many of the configuration options need more detailed 
documentation or I'll have to work through the code to see exactly what 
it's trying to accomplish.  For example, it took me quite awhile to dig 
out how postfix handles CIDR notation.

The pipeline architecture of qmail has been instrumental at making 
third-party additions incredibly simple. You can easily plug in special 
debugging modules, and even tee off things so you can test new modules 
in parallel with real operations.  Before spamdyke was available, I had 
developed a number of homebrew modules for spam analysis and control.  
That said, qmail isn't 100% sendmail compatible, so occasionally I ran 
into issues with unhandled sendmail options (until patched).  I don't 
know whether postfix suffers from the same issue yet.

Since my Qmail based system does not inherently support IPV6 and would 
require significant patching I'm committed to move to Postfix before 
this becomes necessary.  However, Postfix configuration is far more 
complex if you are someone that likes to understand the purpose of each 
option and it's impact to other options.  I will also miss the 
simplicity of making a split-horizon caching DNS service via 
dnscache/tinydns when I need to go to IPV6 which is an important piece 
of any email system in a private networked LAN.
