私のDebianワークステーションはcourier-mtaをインストールしません。コマンドはaptitude install courier-mtaエラーなしで完了しているように見えますが、実際にはsendmailをインストールします。
私がしたこと
メール転送エージェントを提供するパッケージをインストールせずに起動します。
dpkg --get-selections 'courier*' 'sendmail*' 'exim*' sensible-mda | awk '{print $1}' | xargs sudo dpkg --purge --force-depends

次に courier-mta をインストールします。
root@treebeard:/etc/logcheck/violations.ignore.d$ sudo aptitude install 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

質問
courier-mtaはエラーなくインストールされているようですが、courier-mtaはまだインストールされていません。代わりに sendmail がインストールされます。

歴史
これはDebian Wheezy（安定）ボックスです。 Debian Jessy（テスト）を実行していましたが、次の/etc/apt/preferencesファイルを介してWheezyにダウングレードしました。
Package: *
Pin: release a=stable
Pin-Priority: 1001
次に、/etc/apt/sources ファイルを次のように変更します。
deb http://ftp.debian.org/debian wheezy main non-free contrib
deb http://security.debian.org/ wheezy/updates main contrib non-free
そして思い出せない一連のapt-get/dpkgコマンドを通して。欲もたくさんした記憶が出ますね。
質問
courier-mtaをインストールしようとすると、なぜsendmail-binが代わりにインストールされるのですか？

問題を提起する前に、通常はクリーンな仮想イメージをテストして、問題が正しく構成されていないことを確認してください。
Debian 安定 (gasp) 仮想マシン:
apt-get install courier-mta sensible-mda
すでに作業中です。
dpkg -l|grep -e mta -e courier -e exim -e sendmail -e sensible
