/etc/aliases 編集にもかかわらず、[email protected] でメールを送信

まず、私が追加/修正した項目は次のとおりです。/etc/postfix/main.cf文書：

mydomain = domain.com
myorigin = $mydomain
relayhost = email-smtp.us-east-1.amazonaws.com:25
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl/amazon-ses
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
smtp_use_tls = yes
smtp_tls_security_level = encrypt
smtp_tls_note_starttls_offer = yes
header_checks = regexp:/etc/postfix/header_checks

これでテストメールを送ると...

$ sudo sendmail [email protected]
To: [email protected]
From: [email protected]
Subject: Test email!
This is just a test email.
.

メールログを確認してください（/var/log/mail.log)、私はこれを見る:

Feb 17 04:23:16 hostname postfix/pickup[6226]: B3DD4137ED: uid=0 from=<root>
Feb 17 04:23:16 hostname postfix/cleanup[6230]: B3DD4137ED: replace: header From: [email protected] from local; from=<[email protected]> to=<[email protected]>: From: "WebsiteName Alerts (no reply)" <[email protected]>

Feb 17 04:23:18 hostname postfix/qmgr[6144]: B3DD4137ED: removed

ご覧のとおり、ログが表示され、[email protected]コマンドで具体的に述べた[email protected]ようにfrom見えます。[email protected]sendmail

私の修正にもかかわらず/etc/エイリアス次のファイル：

# /etc/aliases
mailer-daemon: [email protected]
postmaster: [email protected]
nobody: [email protected]
hostmaster: [email protected]
usenet: [email protected]
news: [email protected]
webmaster: [email protected]
www: [email protected]
ftp: [email protected]
abuse: [email protected]
noc: [email protected]
security: [email protected]
root: [email protected]

では、問題は[email protected]システムのデフォルトのメールアドレスをどのように設定しますか？つまり、rootユーザーのEメールアドレス[email protected]をからどのように変更しますか[email protected]？

これが重要な場合、私のシステムはDebian 7（Wheezy）64ビットを実行しています。

答え1

ユーザー名とドメインの組み合わせに加えて、デフォルトの返信メールアドレスはありません。 sudo を使用して sendmail を呼び出すと、rootユーザー名を使用してエンベロープ返信アドレスを生成します。この動作を変更するには、-fsendmail でスイッチを使用します。

   -fname Sets the name of the ``from'' person (i.e., the envelope  sender
          of the mail).  This address may also be used in the From: header
          if that header is missing during initial submission.  The  enve‐
          lope sender address is used as the recipient for delivery status
          notifications and may also appear in a Return-Path: header.   -f
          should only be used by ``trusted'' users (normally root, daemon,
          and network) or if the person you are trying to  become  is  the
          same  as  the  person  you are.  Otherwise, an X-Authentication-
          Warning header will be added to the message.
