Configuré postfix en CentOS e intenté configurar phpmailer con autenticación smtp.
PHPMailersolo funcionarási pongo 0.0.0.0/0 debajomis redesen postfix main.conf
mynetworks = 127.0.0.0/8, [::ffff:127.0.0.0]/104, [::1]/128, 0.0.0.0/0
Pero en este hilo (¿Cómo configuro PostFix para permitir que otras máquinas envíen correos electrónicos a través de él?) Alguien dijoNo pongas 0.0.0.0/0 en mynetworks ya que puede causar problemas de spam, etc.
¿Alguien puede aconsejarme qué debo hacer para mantener mi servidor libre de problemas de spam y también para que funcione phpmailer?

Respuesta1
Debería configurar phpmailer para conectarse localhost, no al nombre de host de la máquina (que luego usará su dirección IP externa para conectarse).
Localhost puede retransmitir correo a través de postfix mediante mynetworks, pero cuando se conecta con el nombre de host es a través de la dirección IP pública, que no puede retransmitir.
Respuesta2
Podría solucionarlo agregando lo siguiente en postfix /etc/postfix/master.cf.
smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination
El acceso de retransmisión denegado no es solo para PHPmailer... es para cualquier cliente Outlook, Thunderbird, etc. Poner localhost es una solución alternativa, no una solución completa... por ejemplo, cuando PHPmailer/servidor web es un servidor diferente, que está aislado del correo electrónico postfix. servidor no puedes poner localhost..
