PERSONALLY, I think this is a bad idea but... Relay mail via Google SMTP with Postfix https://blog.wormly.com/2008/11/05/relay-gmail-google-smtp-postfix/ Using Google’s SMTP service to relay your outbound mail is a handy way to be able to send mail from Amazon EC2 instances, or other machines running IP addresses considered to be of dubious quality in the spam fighting world. It’s also quite valuable in that your outbound emails will appear in your GMail sent messages folder and hence appear inline in conversations when your users reply. Setup Instructions These instructions are developed for Centos 5.2 – but no doubt they can be applied to other distributions with minimal modification. Ensure that you have Postfix: |yum install postfix -y| We need to create the client keys for the TLS connection to Google’s SMTP service – and to do that we first need to become our own certificate authority (CA): |/etc/pki/tls/misc/CA -newca| Follow the prompts and make intelligent responses. Now, create the client keys/certs (again with intelligent responses, and ensuring you use the same common name and country code): |cd /etc/postfix openssl genrsa -out postfixclient.key 1024 openssl req -new -key postfixclient.key -out postfixclient.csr openssl ca -out ./postfixclient.pem -infiles postfixclient.csr | Now you can configure Postfix accordingly. Add these to the top of /etc/postfix/main.cf |relayhost = [smtp.gmail.com]:587 smtp_connection_cache_destinations = smtp.gmail.com relay_destination_concurrency_limit = 1 default_destination_concurrency_limit = 5 smtp_sasl_auth_enable=yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_use_tls = yes smtp_sasl_security_options = noanonymous smtp_sasl_tls_security_options = noanonymous smtp_tls_note_starttls_offer = yes tls_random_source = dev:/dev/urandom smtp_tls_scert_verifydepth = 5 smtp_tls_key_file=/etc/postfix/postfixclient.key smtp_tls_cert_file=/etc/postfix/postfixclient.pem smtp_tls_enforce_peername = no smtpd_tls_req_ccert =no smtpd_tls_ask_ccert = yes soft_bounce = yes | And store your password in /etc/postfix/sasl_passwd |gmail-smtp.l.google.com username@yourdomain.com:password smtp.gmail.com username@yourdomain.com:password | (Note that if you’re using a regular gmail account instead of /Google Apps For Your Domain/, you would use username@gmail.com above) Get Postfix to parse the password file: |postmap /etc/postfix/sasl_passwd| Optionally configure Postfix to run on a different port (so as not to clash with your regular SMTP relay): Open /etc/postfix/master.cf and change the first line to: |10025 inet n - n - - smtpd | Now start Postfix! |service postfix start| And add it to your startup scripts: |ln -s /etc/init.d/postfix /etc/rc3.d/S96postfix| Filed under: Servers https://blog.wormly.com/category/servers/ — Jules @ 5:06 pm - November 5, 2008 :: Read comments » https://blog.wormly.com/2008/11/05/relay-gmail-google-smtp-postfix/#comments ~~~~~~~~~~~~~~~~~~~~~~~~~~~ I'm sure you've need this -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
