Bingo, RHEL5 comes with Postfix 2.3.3 and doesn't have support for
mysql/pgsql tables - which are kinda popular, y'know. You can go and
get the centosplus package that includes those, but then of course any
updates will clobber it, and...

That's probably why a lot of the "how to setup a complete mail system"
guides I've seen are written for Debian-type systems. :)

Actually, it's better. On some distros I found Postfix packages that

Well, it works OK and doesn't generate any problems. For me.

Postfix integration is okay as it is. Several people have pointed out why and
I agree with all statements. What hasn't been mentioned yet is the tools you
have access to, if you run Postfix on an Debian/Ubuntu system.

I moved away from RH-like systems two years ago because it's a PITA to get all
the programs you want when you build a mail server. You can get dkim-milter,
amavisd, SpamAssassin etc. pp. through Dag Wieers repository, but then you
break this other dependency and this doesn't work anymore or you spent weeks
waiting for a bug fix.

I haven't seen this on Ubuntu - minor deviations not taken into account.

Looking at the mail system as a whole makes Debian/Ubuntu interesting to me.

dynamicmaps work and don't get into my way. That's perfect for me. On SASL I
don't agree where LaMont puts the configuration file, but then I don't want to
be dogmatic about this either.

The real bad thing is you set it up and it just works. You don't get any
reason to play with once you've set it up. Which is bad, because it's fun. ;)

No, it is a fine Postfix port. There is no reason to avoid it. The dynamic
tables make it easy to add additional table types without re-installing
Postfix or building a Postfix that supports all possible table types. This
Postfix is at least as good as that on other Linux systems.

Ubuntu may or may be quirky, but it is not Postfix that makes it so.
The (really Debian) changes you see in Ubuntu cleanly integrate Postfix
into the rest of the system, making SASL, loadable tables, ... fit more
organically into the larger system. And unlike the MacOSX laptop mode,
the changes are robust and reasonably well thought out.

Good system release engineering is often under-appreciated, lets not
give it a bad name here.

If Unix systems had a much more API for building and using shared
libraries, some of the Ubuntu code would be a nice addition to Postfix.

I have several generations of LaMont's patches.

I have no problem with dynamically-linked maps (though it further
complicates chrooted operation). The problem is that it requires
that Postfix's own libraries are also dynamically linked (libutil,
libglobal, and likely more). 

I have no time to convert and test all supported platforms for
dynamically linked Postfix libraries, I have no time to maintain
build procedures for static and for dynamic linking as it doubles
the number of tests that need to be done, I do not want to drop
supported platforms, and I do not want to make Postfix dependent
on libtool and autobloat.

The design decision in the Debian/Ubuntu Postfix packages the most often 
causes commentary here is to enable chroot by default.  Personally, I like 
it, but it does add some complexity and add to the number of people needing 
help.

How to accomplish most things you need to do with the chroot is reasonably 
well covered in the Ubuntu documentation.  There are also distro specific 
support resources that can help.

We are shipping (and I don't recall which release it arrived in, it may 
just be in the development release) a script to automate removing the 
chroot for people that don't want it.

Yes, everything in Debian is 'somewhat odd'. It's what makes Deb Deb.

I don't want to start a flame war, but I would like to hear what  
people

think about things like "dynamicmaps" and other oddities of the Ubuntu
Postfix configuration.


I looked at Debian a long time ago and decided that postfix and SSL  
and all the services I wanted to run were complex enough that I didn't  
want to add another layer of complication to that.


I don't think anything Debian does is bad per se, but it is different.  
In my case I decided that different was bad.  With a base of FreeBSD  
I've had a lot less trouble getting help than I think I would have  
otherwise.


I also really like portinstall and portupgrade more than rpm or apt-get.

This has been a Debian feature for a long time, a perfectly fine idea
to separate table drivers from Postfix, so that a single base Postfix
package can be shipped, and table support is provided shared libraries
available for people who need said tables.

Ubuntu is a Debian derivative, and it is not surprising to see this
reflected in how they package Postfix.

On the whole, I've not heard of LaMont Jones adding anything particularly
to Postfix. The reasons some of the these changes are not in the official
distribution is that is difficult to support these for all platforms...

I am thinking of switching to Ubuntu 8.10 LTS server, however when I

I don't want to start a flame war, but I would like to hear what people
