Hi all
I'm having trouble using my fresh install of postfix with Blue mind and as I'm not an expert, I don't know how to get rid of this issue.

I have installed Blue mind on a Ubuntu 14.04 LTS version

My emails go to spam with gmail.

Here are the different elements :

my /etc/hosts file :

127.0.0.1 mail.mydom.com mail localhost
127.0.1.1 mail.mydom.com mail
178.XX.17.XX mail.mydom.com
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

hostname -f shows : mail.mydom.com

my /etc/postfix/main.cf :

smtpd_banner = mail.mydom.com
biff = no

append_dot_mydomain = no

myhostname = mail.mydom.com
relayhost =

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
local_recipient_maps = $alias_maps

#mydestination = $myhostname
mydestination = mail.mydom.com
mynetworks = 127.0.0.0/8, XX.XX.XX.X/24 #i hide the public ip here
message_size_limit = 10485760

irtual_transport = error:mailbox does not exist
virtual_mailbox_domains = hash:/etc/postfix/virtual_domains
virtual_mailbox_maps = hash:/etc/postfix/virtual_mailbox
virtual_alias_maps = hash:/etc/postfix/virtual_alias
transport_maps = hash:/etc/postfix/transport, hash:/etc/postfix/master_relay_transport

recipient_delimiter = +

milter_protocol = 2
milter_default_action = accept
smtpd_milters = inet:localhost:12301
non_smtpd_milters = inet:localhost:12301

# SMTP/TLS
smtpd_tls_security_level=may
smtpd_tls_cert_file=/etc/ssl/certs/bm_cert.pem
smtpd_tls_key_file=/etc/ssl/certs/bm_cert.pem
smtpd_tls_CAfile=/var/lib/bm-ca/cacert.pem
smtpd_tls_mandatory_protocols=!SSLv2,!SSLv3

# SMTP authentication
smtpd_sasl_auth_enable=yes
broken_sasl_auth_clients=yes
smtpd_sasl_security_options=noanonymous
smtpd_recipient_restrictions=permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
smtpd_sasl_authenticated_header=yes

---------------------

I also installed opendkim and dns is ok. Spam detection is alright too on some sites.

Here is the original email send. There is something I don't understand it says "received from local.localdomain ..." I don't know what it is and I can't delete it.

Check out the original mail :

Well It says that dkim failed, it's because I just updated the dkim key on dns records.

Any clue,?
thanks in advance
