Hi,
Sorry for not sharing the solucion.
Here she goes.
in my case, there were two things that were causing this hops problem. The content_filter and Relayhost.
First - In main.cf I change the content_filter = smtp:[localhost]:10024 to content_filter =
Second - I had to configure my relayhost with authentication.
These are the steps that I use to set up Postfix to use SMTP Authentication to send mail through a relay host.
Set up a password maps file (/etc/postfix/sasl_passwd) as follows:
mail.ispserver.com username:password
chown root:root /etc/postfix/sasl_passwd; chmod 600 /etc/postfix/sasl_passwd
postmap /etc/postfix/sasl_passwd
In /etc/postfix/main.cf:
relayhost = mail.ispserver.com
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =
Best regards and again sorry for not sharing the solucion sooner
