Minha estação de trabalho Debian não instalará o correio-mta. O comando aptitude install courier-mta parece estar completo sem erros, mas na verdade instala o sendmail.
O que eu fiz
Vou começar sem nenhum pacote instalado que forneça o agente de transferência de mensagens:
dpkg --get-selections 'courier*' 'sendmail*' 'exim*' sensible-mda | awk '{print $1}' | xargs sudo dpkg --purge --force-depends
...
root@treebeard:/etc/logcheck/violations.ignore.d$ dpkg -l 'courier*' 'sendmail*' 'exim*' sensible-mda

un exim4 <none> (no description available)
dpkg-query: no packages found matching courier*
dpkg-query: no packages found matching sendmail*

E, em seguida, instale o correio-mta:
root@treebeard:/etc/logcheck/violations.ignore.d$ sudo aptitude install courier-mta
The following NEW packages will be installed:
courier-authdaemon{a} courier-authlib{a} courier-authlib-userdb{a} courier-base{a} courier-mta

Preconfiguring packages ...
Configuring courier-base
------------------------
Courier uses several configuration files in /etc/courier. Some of these files can be replaced by a subdirectory whose contents are concatenated and treated as a single, consolidated, configuration file.
The web-based administration provided by the courier-webadmin package relies on configuration directories instead of configuration files. If you agree, any directories needed for the web-based administration tool
will be created unless there is already a plain file in place.
Create directories for web-based administration? no
Configuring courier-mta
-----------------------
Please specify a valid email domain. Most header rewriting functions will append this domain to all email addresses which do not specify a domain, such as local accounts.
Default domain: fake.domain
Please specify a valid value for the "From" header for mail delivery notifications. These notifications cannot be sent without that setting.
"From" header for delivery notifications: [email protected]

O problema
O
courier-mta parece ter sido instalado sem erros, e ainda assim o courier-mta não está instalado. Em vez disso, o sendmail está instalado:

História
Esta é uma caixa do Debian Wheezy (estável). Estava rodando o Debian Jessy (testing), mas eu fiz downgrade para o Wheezy por meio deste arquivo / etc / apt / preferences:
Package: *
Pin: release a=stable
Pin-Priority: 1001
e alterando o arquivo / etc / apt / sources para:
deb http://ftp.debian.org/debian wheezy main non-free contrib
deb http://security.debian.org/ wheezy/updates main contrib non-free
e por meio de uma longa série de comandos do apt-get / dpkg que eu não me lembro. Eu lembro de ter sido muito palavrões.
A questão
Por que, quando tento instalar o courier-mta, o sendmail-bin está sendo instalado?
