/opt/csw/etc/exim/exim.conf作成

/opt/csw/etc/exim/exim.conf.CSWをベースに以下を変更。

local_domains設定

/etc/mail/local-host-namesに列挙してあるドメイン名をdomainlist local_domainsに記述(“:”区切り)。

domainlist local_domains = localhost : example.jp

Maildir配送に変更

local_delivery定義を変更して、デフォルトをMaildir配送にします。

local_delivery:
  driver = appendfile
  directory = $home/Maildir
  maildir_format = true
  mode_fail_narrower = false
  delivery_date_add
  envelope_to_add
  return_path_add
# group = mail
# mode = 0660

/opt/csw/etc/exim/aliases作成

/etc/mail/aliasesをコピーします。sendmailと違ってnewaliasesは不要です。

eximデーモン起動

# cd /;env -i /etc/init.d/cswexim start

動作確認

不正中継チェック

以下のチェックサービスで不正中継動作しないことを確認。

• nanet – 第三者中継調査
• 第三者中継チェック RBL.JP

以前、とあるサイトにtelnetすると、SMTPポートに接続してきてチェック、ってサービスがあったと思うのですが、なくなっちゃったのですかね。普通にログインプロンプトが出てきて驚いちゃいました。

ローカル配送確認

tcp/25に直接接続してローカル配送の確認。

$ telnet localhost 25
:

最後にリモートからメール受信できることを確認して終了。
