PostFix Error 550

It appears in the sys log error log that I can not send mail because my server can not be verified.

I have been able to configure my Debian server with many things but I have never been able to figure out the mail system to be able to send messages. I am running Debian GNU/Linux 8.5.0 Jessie and postfix postconf -d | grep mail_version mail_version = 2.11.3 milter_macro_v = $mail_name $mail_version

I am a experienced programmer with Debian, c, c++, php and other languages. I would truly appreciate some help. I am hopeless lost on this subject. is the name server for my web-site. The mx records are pointed to the as I currently use them as a mail server. I also have an other web-site that all A records point to my server. I tried to configure it for that but it did not work either. Here is my file.

See /usr/share/postfix/ for a commented, more complete version Debian specific: Specifying a file name will cause the first line of that file to be used as the name. The Debian default is /etc/mailname. myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no

appending .domain is the MUA's job.

append_dot_mydomain = no

Uncomment the next line to generate "delayed mail" warnings delay_warning_time = 4h

readme_directory = no

TLS parameters

smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key


smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for information on enabling SSL in the smtp client.

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination

myhostname =

alias_maps = hash:/etc/aliases

alias_database = hash:/etc/aliases

myorigin = /etc/mailname

mydestination =,, , localhost

relayhost =

mynetworks = [::ffff:]/104 [::1]/128

mailbox_command = procmail -a "$EXTENSION"

mailbox_size_limit = 0

recipient_delimiter = +

inet_interfaces = all

And here is the error log for trying to send an e-Mail.

Sorry my file did not paste correctly the first time. This is my first time using a forum. I tired to fix it but it won't work.
