Postfix - as mensagens devolvidas não são enviadas para o postmaster

Question

Eu proibir e rejeitar alguns domínios / IPs de spammer, via:

smtpd_recipient_restrictions = check_sender_access regexp:/etc/postfix/client_checks, ...

arquivo client_checks:

/\@domain\./  REJECT

e funciona bem, mas quero receber uma notificação sobre postmaster ou email especial ([email protected]) toda vez que o email for recusado e a mensagem de falha de entrega for enviada ao remetente (spammer).

Eu configurei o seguinte já no main.cf, mas não funciona:

notify_classes = bounce
bounce_notice_recipient = [email protected]

Por favor, você poderia me ajudar a descobrir o que estou fazendo de errado?

    

Answer 1

Você precisa ajustar o parâmetro notify_classes para ser notificado sobre os e-mails rejeitados. Você pode adicionar o policy para ser notificado sobre emails rejeitados por políticas. As opções são explicadas aqui:

notify_classes (default: resource, software)

The list of error classes that are reported to the postmaster. The default is to report only the most serious problems. The paranoid may wish to turn on the policy (UCE and mail relaying) and protocol error (broken mail software) reports.

NOTE: postmaster notifications may contain confidential information such as SASL passwords or message content. It is the system administrator's responsibility to treat such information with care.

The error classes are:

bounce (also implies 2bounce)

Send the postmaster copies of the headers of bounced mail, and send transcripts of SMTP sessions when Postfix rejects mail. The notification is sent to the address specified with the bounce_notice_recipient configuration parameter (default: postmaster).

2bounce

Send undeliverable bounced mail to the postmaster. The notification is sent to the address specified with the 2bounce_notice_recipient configuration parameter (default: postmaster).

data

Send the postmaster a transcript of the SMTP session with an error because a critical data file was unavailable. The notification is sent to the address specified with the error_notice_recipient configuration parameter (default: postmaster). This feature is available in Postfix 2.9 and later.

delay

Send the postmaster copies of the headers of delayed mail (see delay_warning_time). The notification is sent to the address specified with the delay_notice_recipient configuration parameter (default: postmaster).

policy

Send the postmaster a transcript of the SMTP session when a client request was rejected because of (UCE) policy. The notification is sent to the address specified with the error_notice_recipient configuration parameter (default: postmaster).

protocol

Send the postmaster a transcript of the SMTP session in case of client or > server protocol errors. The notification is sent to the address specified with the error_notice_recipient configuration parameter (default: postmaster).

resource

Inform the postmaster of mail not delivered due to resource problems. The > notification is sent to the address specified with the error_notice_recipient configuration parameter (default: postmaster).

software

Inform the postmaster of mail not delivered due to software problems. The > notification is sent to the address specified with the error_notice_recipient configuration parameter (default: postmaster).

Examples:

notify_classes = bounce, delay, policy, protocol, resource, software
notify_classes = 2bounce, resource, software
