Hi, thanks for the answers. I guess I need to dig deeper into apt and 
dpkg. I deinstalled at and the courier packages then did (soory that 
some of it is in German, but you can see the packet names):

# apt-get  install at
Paketlisten werden gelesen... Fertig
Abhängigkeitsbaum wird aufgebaut... Fertig
Die folgenden zusätzlichen Pakete werden installiert:
  courier-authdaemon courier-authlib courier-authlib-userdb 
courier-base courier-mta

So I installed what it suggested.

But, looking into the package I can see that it needs just an MTA, as 
was described to me:

# apt-cache showpkg at
Package: at
Versions:
3.1.10(/var/lib/apt/lists/ftp.hosteurope.de_pub_linux_debian_dists_etch_main_binary-arm_Packages)(/var/lib/dpkg/status)

Reverse Depends:
  mirror,at
  lsb-core,at
  gnome-schedule,at
  gato,at
  devscripts,at
Dependencies:
3.1.10 - libc6 (2 2.3.5-1) libpam0g (2 0.76) mail-transport-agent (0 
(null)) lsb-base (2 3.0-10)
Provides:
3.1.10 -
Reverse Provides:

As suggested I tried the following:

# apt-get install at exim4-daemon-light
Paketlisten werden gelesen... Fertig
Abhängigkeitsbaum wird aufgebaut... Fertig
Die folgenden zusätzlichen Pakete werden installiert:
  courier-authdaemon courier-authlib courier-authlib-userdb 
courier-base exim4-base exim4-config
Vorgeschlagene Pakete:
  eximon4 exim4-doc-html exim4-doc-info gnutls-bin openssl 
libmail-spf-query-perl
Die folgenden NEUEN Pakete werden installiert:
  at courier-authdaemon courier-authlib courier-authlib-userdb 
courier-base exim4-base exim4-config exim4-daemon-light

So apt-get wanted to install courier and exim4!

Then tried:

 aptitude install at exim4-daemon-light
Paketlisten werden gelesen... Fertig
Abhängigkeitsbaum wird aufgebaut... Fertig
Lese erweiterte Statusinformationen
Initialisiere Paketstatus... Fertig
Lese Task-Beschreibungen... Fertig
Erzeuge Tag-Datenbank... Fertig
Die folgenden NEUEN Pakete werden zusätzlich automatisch installiert:
  exim4-base exim4-config

That seemed to work, but with errors as exim etc. needs some 
configuration. But that has solved the dependency problem as far as I 
can see.

So thanks very much for the tips.

Cheers Brian
