Postfix configuration

forums

Hi,

Sorry for my english, I'm french.

I have some doubts about my Postfix configuration.

I have a private mail server, at my home, allowing me to have my personal e-mails ( @my_domain.fr )

My architecture is the following one (on Raspberry Pi with Raspbian):

- 1 mail server with Postfix, Dovecot, Amavis, Spamassassin, ClamAV

- 3 others severs, not mail servers

I can send and receive e-mails, from inside and outside without any problem.

I use a SMTP relay (my provider SMTP).

I have a domain and the MX record is OK.

But I'm not sure about my Postfix configuration.

Here it is:

* main.cf:

smtpd_banner = $myhostname ESMTP $mail_name (Raspbian)
biff = no
append_dot_mydomain = no
#delay_warning_time = 4h
readme_directory = no

smtp_sasl_password_maps = hash:/etc/postfix/sasl/sasl_passwd
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination

Is there OK or did I forget/badly parametrize something ?


Thank's.
