E-mail enviado via [email protected] apesar de modificar / etc / aliases

Question

Primeiro, aqui estão as entradas que eu adicionei / modifiquei no arquivo /etc/postfix/main.cf :

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

Agora, se eu enviar um e-mail de teste assim ...

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

e verifique o registro de e-mail ( /var/log/mail.log ), eu vejo isto:

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 04:23:16 hostname postfix/cleanup[6230]: B3DD4137ED: message-id=<[email protected]>
Feb 17 04:23:16 hostname postfix/qmgr[6144]: B3DD4137ED: from=<[email protected]>, size=353, nrcpt=1 (queue active)
Feb 17 04:23:18 hostname postfix/smtp[6232]: B3DD4137ED: to=<[email protected]>, relay=email-smtp.us-east-1.amazonaws.com[107.22.250.234]:25, delay=25, delays=24/0.03/0.93/0.58, dsn=2.0.0, status=sent (250 Ok 0000013ce6644ae6-69927d25-c4e1-4f25-8ad4-b85b59318e84-000000)
Feb 17 04:23:18 hostname postfix/qmgr[6144]: B3DD4137ED: removed

Como você pode ver, o log mostra [email protected] e [email protected] como from , embora eu tenha declarado especificamente [email protected] no comando sendmail .

Isso também, apesar de modificar meu arquivo / etc / aliases da seguinte forma:

# /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]

Então, a pergunta é: como faço [email protected] o endereço de e-mail padrão para o sistema? Dito de outra forma, como eu mudo o endereço de e-mail do usuário root de [email protected] para [email protected] ?

Caso isso seja importante, meu sistema está rodando Debian 7 (Wheezy) 64-bit.

    

Answer 1

Não há endereço de email de retorno padrão diferente do nome de usuário combinado com o nome do domínio. Quando você invoca o sendmail com o sudo, ele usa o nome do usuário root para fazer o endereço de retorno do envelope. Para mudar este comportamento use a opção -f com sendmail:

   -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.
