まあ，いつもくせ者なのですが😓 Debian流儀ではどのようにすべきなのかChatGPTやGeminiに聞きながらやっています．<\/p>\n\n\n\n

長年醸成してきたsendmail.mc<\/code>をsendmail-cfユーティリティーでささっとsendmail.cf<\/code>にするだけ，と思いましたが，そもそもどこにsendmail.mc<\/code>を置けばよいのから判りません．<\/p>\n\n\n\n

結論的には，\/etc\/mail\/<\/code>にsendmail.mc<\/code>を置いて，sendmailconfig<\/code>というスクリプトを走らせれば良いということが判りました．<\/p>\n\n\n\n

これがまたくせ者でした．これまでやってきたSlackwareでの方法は，ワークディレクトリー1<\/a><\/sup>Slackwareでは\/usr\/src\/sendmail-cf\/cf\/cf<\/code>．<\/span>に\u30db\u30b9\u30c8\u540d_\u65e5\u4ed8-1.mc<\/code>というファイルを作って，これに対して，<\/p>\n\n\n\n

make \u30db\u30b9\u30c8\u540d_\u65e5\u4ed8-1.cf<\/code><\/pre>\n\n\n\n
とすれば，\u30db\u30b9\u30c8\u540d_\u65e5\u4ed8-1.cf<\/code>ができます．そこで，そのファイルを\/etc\/mailに移して，<\/p>\n\n\n\n
ln -s  \u30db\u30b9\u30c8\u540d_\u65e5\u4ed8-1.cf  sendmail.cf<\/code><\/pre>\n\n\n\n
として使っていました．<\/p>\n\n\n\n
ところが，Debianのsendmailconfigはそれを許してくれません．まず元の\u30db\u30b9\u30c8\u540d_\u65e5\u4ed8-1.mc<\/code>ファイルを\/etc\/mail<\/code>に起き，sendmail.mc<\/code>という名前にしないといけません．そこは逆らって，\u30db\u30b9\u30c8\u540d_\u65e5\u4ed8-1.mc<\/code>のまま，\/etc\/mail<\/code>に置いて，sendmail.mc<\/code>にsymlinkを貼りました．<\/p>\n\n\n\n
そこで，sendmailconfigを実行したところ，sendmail.cf<\/code>はできますが，symlinkは解除されて，\u30db\u30b9\u30c8\u540d_\u65e5\u4ed8-1.mc<\/code>を基にしたsendmail.mc<\/code>が作られて，内容が一部改変されています．<\/p>\n\n\n\n
内容の改変はたいしたことないので，その内容を元の\u30db\u30b9\u30c8\u540d_\u65e5\u4ed8-1.mc<\/code>に施しておきました．今後どのようにしたら解りやすいのか考えたいと思いますが，とりあえずはできたから良いです．<\/p>\n\n\n\n
sendmailはまだ起動していません．動作確認にはけっこう手間がかかりそうに思います．<\/p>\n","protected":false},"excerpt":{"rendered":"
