Tengo un cliente que intenta utilizar postfix para enviar correos electrónicos con SMTP. Parece que postfix analizará los atributos del correo electrónico correctamente, pero antes de enviar el correo electrónico comienza a procesarlo nuevamente. Esto sucede en un bucle sin fin. Puse postfix en modo de depuración y produje un archivo de registro que se ve casi exactamente igual a un archivo de registro producido con mi propio sistema hasta el punto en que repite el análisis del correo electrónico.
El final del registro del cliente:
postfix/smtpd[29586]: connection closed
postfix/smtpd[29586]: connection established
Mi final de registro:
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)
postfix/qmgr[19812]: 0D65814D: removed

No hay información sobre el correo electrónico rechazado en el registro de cola. Correr mailq > mailqueue.txtno produjo ninguna información significativa. También le pedí al cliente que vaciara la cola postqueue -fy reiniciara postfix, pero nada ayudó.
¿Qué causa que Postfix repita el análisis del correo electrónico en lugar de enviarlo?

authnz.prod-c15a-awsuse.proofpoint.com[205.220.189.150] dijo: 530 5.7.0 Se requiere autenticación (en respuesta al comando MAIL FROM)
Parece que no se está autenticando en el relé que ha configurado.
relayhost = authnz.proofpoint.com:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/smtp_password
Verifique el contenido de /etc/postfix/smtp_password. Específicamente,postfix le indica quehaga coincidir el formato entre el valor del host de retransmisión y la clave de búsqueda del mapa.
Si especifica un puerto TCP no predeterminado (como ":submission" o ":587") en el destino del host de retransmisión, debe utilizar el mismo formulario en el archivo smtp_sasl_password_maps.
Si esto resulta ser un problema con esa asignación de contraseñas, no olvide actualizar la caché indexada emitiendo postmap /etc/postfix/smtp_passwordy considere qué debería suceder con los mensajes aún por entregar en su cola.puededesea actualizar los destinatarios y remitentes afectados a través de alguna otra ruta que no sea entregar (posiblemente muchas) notificaciones de no entrega.
