It is sometimes useful to be able to use the normal mail command. For example, some tools like smartctl can be configured to send emails on error. If you create a google mail account, you can use postfix to send mail using this google account. The following assume you are logged in as root. 1. Get a google mail account a gmail.com 2. Install some basic libraries: Code: apt-get install libsasl2-2 sasl2-bin libsasl2-modules procmail 3. Install postfix. This will start the configure. Select the "Internet Site" configuration. For the "Relay Host" enter "smtp.gmail.com:587". Code: apt-get install postfix 4. Create the password file for your account. Put the following in /etc/postfix/sasl_passwd: Code: smtp.gmail.com:587 YourUserID@gmail.com:YourPassWord 5. Create the hash file with the following command Code: cd /etc/postfix postmap sasl_passwd 6. Secure the passwd files: Code: chown root:root /etc/postfix/sasl_passwd* chmod go-rwx etc/postfix/sasl_passwd* 7. Update the sasl config: Code: echo 'pwcheck_method: saslauthd' >> /etc/postfix/sasl/smtpd.conf echo 'mech_list: plain login' >> /etc/postfix/sasl/smtpd.conf 8. Add the following lines to the bottom of /etc/postfix/main.cf Code: ## SASL Settings # This is going in to THIS server smtpd_sasl_auth_enable = yes # We need this smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtpd_sasl_local_domain = $myhostname smtp_sasl_security_options = noanonymous smtp_sasl_tls_security_options = noanonymous smtpd_sasl_application_name = smtpd smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination broken_sasl_auth_clients = yes smtp_tls_loglevel = 1 smtpd_tls_loglevel = 1 smtp_tls_security_level = may smtp_tls_session_cache_database = btree:/var/run/smtp_tls_session_cache tls_random_source = dev:/dev/urandom disable_dns_lookups = yes inet_interfaces = all 9. Restart postfix: Code: postfix stop postfix start 10. Test mail (If it doesn't work, check /var/log/mail.log): Code: echo Hello \| mail -s Test <emailAddress> 11 (Optional): Fix local email. This allows mail to a local user. Ex. "echo Hello \| mail -s Test root": Code: chown mail:mail /var/mail chmod chmod g=rwx,o=rx /var/mail 12 (Optional): Create a forward so local email is sent elsewhere. Log in as the user who's mail will be forwarded. Edit ~/.forward and put in the email where the mail will be forwarded. I think I captured everything. There was a bit of trial and error setting this up the first time, but I think this captures the necessary steps. The following link helped me quite a bit: http://behindmyscreen.newsvine.com/_new ... easy-steps
