mailコマンドを使ってメールを送信すると送信元アドレスが [アカウント]@[ホスト].[ドメイン] となってしまう。
本当はmailコマンドで送った時、[アカウント]@[ドメイン]となって欲しい
main.cfでは、myorigin をちゃんと$mydomainを指定している。
# cat /etc/postfix/main.cf myorigin = $mydomain
mailコマンドが使用するmta設定がsendmailのままとなっていると、@以下に/etc/sysconf/networkのHOSTNAMEを使用する仕様
# ls -l /etc/alternatives/mta
lrwxrwxrwx 1 root root 26 Oct 30 09:38 /etc/alternatives/mta → /usr/sbin/sendmail.postfix
下記のコマンドで、MTAを切り替えてあげればOK
これで、ただしく@以下がmyorigin で送信されます。
# alternatives --config mta 2 プログラムがあり 'mta' を提供します。 選択 コマンド ----------------------------------------------- *+ 1 /usr/sbin/sendmail.sendmail 2 /usr/sbin/sendmail.postfix Enter to keep the current selection[+], or type selection number:
# ls -l /etc/alternatives/mta lrwxrwxrwx 1 root root 26 Oct 30 09:38 /etc/alternatives/mta -> /usr/sbin/sendmail.postfix
