This is, WHY I use PostgreSQL...  It performance miuch better.

Currently I am running a Test-Installation with Courier-Imap-Proxy,  two
Courier-Imap-Storage-Server and two PostgreSQL Database and a Webserver.

I am using 6 "Sun Fire X4100M2"  with  smallest  Quad-Core  Opteron  and
2x2 GByte of memory.

I have 180 Regular-Users on the  System  and  for  testing  arround  400
foreigners.  It handel currently my 4 own and 3 customer domains.

The next step is to install one or  two  inbound  MTA's  which  do  user
customised virus/spam filtering using courierlocalfilter.  Unfortunately
I have not seen a postfix/exim setup which  is  able  to  do  this  with
seperated Inbound-MTA, IMAP-Proxy and IMAP-Storage.

This is, what bigger ISP are using but it seems, each one  has  to  hack
its own stuff (Freenet, 1&1/GMX, Arcor, T-Online, KabelBW, ...)

Here you would produce per day more  then  2000  False-Positives  in  my

Spamfiltering MUST be individuual and if you give th user options,  like
at <freenet.de>, the user can CHOOSE which he/she want. Global filtering
is VERY dangerous.

And of course, you can not use  /^dsl.*\..*/, /ppp.*\..*/  if  you  have
hosted Domains from your customers, because most customers ARE  on  such

Q:  I am using the courier-suite too,
    but are you able to use Per-User-Quota?

This is NO explanation...  What is better?

I use mailman and courier-mlm and both are working perfectly as I expect

Which tools do you use?

Hmmm, there AFAIK several packages in Debian which modify the behabviour
of other packages in Debian, but there is a  "debconf"  question,  which
ASK  the  administrator,  whether  the  package  should  take  over  the
configuration which the administrator should answer [Ny].
