Tenho um cliente tentando usar o postfix para enviar e-mails com SMTP. Parece que o postfix analisará os atributos do email corretamente, mas antes de enviar o email ele começará a processá-lo novamente. Isso acontece em um loop infinito. Coloquei o postfix no modo de depuração e produzi um arquivo de log que se parece quase exatamente com um arquivo de log produzido com meu próprio sistema até o ponto em que ele repete a análise do email.
Fim do log do cliente:
postfix/smtpd[29586]: connection closed
postfix/smtpd[29586]: connection established
Meu fim do log:
postfix/smtpd[20539]: connection closed
postfix/smtp[20543]: 0D65814D: to=<[email protected]>, relay=10.2.253.96[10.2.253.96]:25, delay=0.17, delays=0.03/0.07/0/0.06, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as O)

Não há informações sobre o e-mail rejeitado no log da fila. A corrida mailq > mailqueue.txtnão produziu nenhuma informação significativa. Também fiz o cliente liberar a fila postqueue -fe reiniciar o postfix, mas nada ajudou.
O que está fazendo com que o postfix repita a análise do email em vez de enviá-lo?

authnz.prod-c15a-awsuse.proofpoint.com[205.220.189.150] disse: 530 5.7.0 Autenticação necessária (em resposta ao comando MAIL FROM)
Parece que você não está se autenticando no relé que configurou.
relayhost = authnz.proofpoint.com:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/smtp_password
Verifique o conteúdo de /etc/postfix/smtp_password. Especificamente,postfix instrui você acorresponda ao formato entre o valor do relayhost e a chave de pesquisa do mapa.
Se você especificar uma porta TCP não padrão (como ":submission" ou ":587") no destino do relayhost, deverá usar o mesmo formato no arquivo smtp_sasl_password_maps.
Se isso realmente for um problema com o mapa de senhas, não se esqueça de atualizar o cache indexado emitindo postmap /etc/postfix/smtp_password- e considere o que deve acontecer com as mensagens que ainda não foram entregues em sua fila, vocêpoderiadeseja atualizar os destinatários e remetentes afetados por alguma outra rota que não a entrega (possivelmente muitas) de notificações de não entrega.
