メールサーバの構築

今回は旧学科メールサーバからの転送を受け取るだけのサーバを立てることにする。

  • Postfix(SMTPサーバ)
  • (imapサーバ)

Postfixのインストール

インストールはapt一発とはいかない。(Ubuntu Serverの場合)

$ sudo apt install postfix

途中で

Package configuration
 
  ┌────────────────────────┤ Postfix Configuration ├────────────────────────┐
  │                                                                         │
  │ Please select the mail server configuration type that best meets your
  │ needs.
  │
  │  No configuration:
  │   Should be chosen to leave the current configuration unchanged.
  │  Internet site:
  │   Mail is sent and received directly using SMTP.
  │  Internet with smarthost:
  │   Mail is received directly using SMTP or by running a utility such
  │   as fetchmail. Outgoing mail is sent using a smarthost.
  │  Satellite system:
  │   All mail is sent to another machine, called a 'smarthost', for
  │   delivery.
  │  Local only:
  │   The only delivered mail is the mail for local users. There is no
  │   network.
  │
  │                                 <Ok>
  │                                                                         │
  └─────────────────────────────────────────────────────────────────────────┘

のような選択肢が出るので、ここはNo configurationを選択する。

Setting-up Postfix

設定ファイルは/etc/postfix/main.cf。雛形が/usr/share/postfixにある。

sudo cp /usr/share/postfix/main.cf.dist /etc/postfix/main.cf
