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 tutorial. You also might want to take a look at Masquerade email address as well.
REF: Postfix SMTP relay to SMTP gmail.com
- First of all, install postfix and remove sendmail:
yum -y install postfix mailx 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 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:
[smtp.gmail.com]:587 user@gmail.com:Password
NOTE: Change user to your username and password to your gmail crredentials.
- Build the password database:
postmap hash:/etc/postfix/sasl_passwd
- Create /etc/postfix/tls_policy file with your Gmail login credentials that looks like below:
[smtp.gmail.com]:587 encrypt
- Build the policy database:
postmap /etc/postfix/tls_policy
- Protect the files with your Gmail login data:
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
- Restart Postfix:
systemctl restart postfix.service
- Set Postifx to start on boot:
systemctl enable postfix.service
- Now try sending a mail, it should reach your Gmail account:
echo test 1 2 | mail -s "Test mail" user@gmail.com
NOTE: Some ISPs will block emails sent using this method. Looking for a work around.
