 +Try a PHP or Perl solution, but does it require SSMTP or MSMTP?
  
-Directions [[http://mhawthorne.net/posts/postfix-configuring-gmail-as-relay.html|based on this page by Matthew Hawthorne]] worked: \\ +Final answer was to configure [[gmail_as_a_relay_on_linux|Gmail as a Relay]]
- +
-1. Make a backup copy of /etc/postfix/main.cf +
- +
-2. Edit /etc/postfix/main.cf to have these settings: +
- +
-<code> +
-# sets gmail as relay +
-relayhost = [smtp.gmail.com]:587 +
- +
-#  use tls +
-smtp_use_tls=yes +
- +
-# use sasl when authenticating to foreign SMTP servers +
-smtp_sasl_auth_enable = yes  +
- +
-# path to password map file +
-smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd +
- +
-# list of CAs to trust when verifying server certificate +
-#smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt +
-# Below is provided by ca-certificates package (Mozilla CA root certificate bundle) +
-smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt +
- +
-# eliminates default security options which are incompatible with Gmail +
-smtp_sasl_security_options = +
- +
-# add debugging +
-debug_peer_list=smtp.gmail.com +
-debug_peer_level=3 +
-</code> +
- +
-2. Add your own Gmail credentials to /etc/postfix/sasl_passwd \\ +
-<code> +
-[smtp.gmail.com]:587  username:password +
-</code> +
- +
-3. Run the following as root: \\ +
-<code> +
-# postmap /etc/postfix/sasl_passwd +
-</code> +
- +
-4. Make sure the /etc/sasl_passwd* files are owned by the postfix user: \\ +
-<code> +
-# chown postfix sasl_passwd* +
-</code> +
- +
-5. Tighten permissions: \\ +
-<code> +
-# chmod 600 sasl_passwd sasl_passwd.db +
-</code> +
- +
-6. Restart postfix: \\ +
-<code> +
-# /etc/init.d/postfix reload +
-</code> +
-or +
-<code> +
-# service postfix restart +
-</code> +
- +
-7. Send a test message: \\ +
-<code> +
-echo 'It works' | mailx -s 'Test message' [email protected] +
-</code> +
- +
-8. Check mutt configuration for proper "From" settings.   +
