This can be used to send mails from your Fedora 19/Amahi 7 HDA and to receive system emails.
To receive emails meant for the root user, you have to Forward System Emails after finishing this.

First of all, install postfix and remove sendmail:

bash code
`yum -y install postfix yum -y remove sendmail`

Add the following to the bottom of the file /etc/postfix/main.cf. You do not need to change anything else in it, as the last setting for any option is the one that is saved.

#### Gmail SSL SMTP Relay #TLS parameters  smtpd_use_tls=yes  smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache  smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache  smtp_tls_note_starttls_offer = yes  smtp_tls_policy_maps = hash:/etc/postfix/tls_policy   #Relay host configuration  relayhost = [smtp.gmail.com]:587   #SASL Configuration  smtp_sasl_auth_enable = yes  smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd  smtp_sasl_security_options = noanonymous  smtp_sasl_mechanism_filter = plain  smtp_sasl_tls_security_options = noanonymous

Create /etc/postfix/sasl_passwd file with your Gmail login credentials that looks like below:

Text
`[smtp.gmail.com]:587 user@gmail.com:Password`

NOTE: Change user to your username and password to your gmail crredentials.

Build the password database:

bash code
`postmap hash:/etc/postfix/sasl_passwd`

Create /etc/postfix/tsl_policy file with your Gmail login credentials that looks like below:

Text
`[smtp.gmail.com]:587 encrypt`

Build the policy database:

bash code
`postmap /etc/postfix/tls_policy`

Protect the files with your Gmail login data:

bash code
`chmod 600 /etc/postfix/sasl_passwd chmod 600 /etc/postfix/sasl_passwd.db chmod 600 /etc/postfix/tsl_policy chmod 600 /etc/postfix/tsl_policy.db chown postfix /etc/postfix/sasl_passwd chown postfix /etc/postfix/sasl_passwd.db chown postfix /etc/postfix/tsl_policy chown postfix /etc/postfix/tsl_policy.db`

Restart Postfix:

bash code
`systemctl restart postfix.service`

Set Postifx to start on boot:

bash code
`systemctl enable postfix.service`

Now try sending a mail, it should reach your Gmail account:

bash code
`echo test 1 2 \| mail -s "Test mail" user@gmail.com`

 {{Code|yum -y install postfix

-Openssl and openssl-perl are needed to generate certificates and create SSL connections to GMail<br>
-Openssl should be installed already, but to be sure: <br>
-{{Code|yum -y install openssl openssl-perl}}
-A Certificate Authority is needed to create the necessary certificates. You can skip the next paragraph if you already have one:<br>
-{{Code|cd /etc/pki/tls/misc
-./CA –newca}}
-*You will be prompted for the file name, hit enter to create a new CA.
-* You will need to enter a passphrase next, be sure to remember it.
-*Choose the Country Name, State or Province Name, Locality Name, Organization Name, and Organizational Unit Name to your liking. Be sure to remember the values, they will be needed in the key creation later.
-*For the Common Name, type “CA” (without quotes).
-*Take defaults for everything else and when prompted enter the passphrase from above.<br>
-Now a key that is sent to Gmail to start the SSL encryption will be created: <br>
-{{Code|cd /etc/pki/tls
-mkdir gmail_relay
-cd gmail_relay
-openssl genrsa -out server.key 1024
-openssl req -new -key server.key -out server.csr}}
-You will be prompted for country etc. like when creating the CA. Enter the same values. <br>
-As Common Name, now enter the name of your server, FQDN or not, your choice. <br>
-{{Code|openssl ca -out server.pem -infiles server.csr}}
-You will need to enter your passphrase again at this point.<br>
-When asked if you want to sign the key, answer  yes, same when asked if to commit it.
