Microsoft Exchange as relay for Elastix 1.6 eMail

You will need to have a valid domain user with an Exchange mailbox to send mail as.

SSH to your Elastix box and run the following commands:

postconf -e 'relayhost = exchange-ip-address'
postconf -e 'smtp_sasl_auth_enable = no'
postconf -e 'smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd'
postconf -e 'smtp_sasl_security_options ='
postconf -e 'mydomain = your-domain-name.com'
postconf -e 'myhostname = elastix-hostname.your-domain-name.com'

echo "exchange-ip-address   domain-username:domain-password" > /etc/postfix/sasl_passwd

chown root:root /etc/postfix/sasl_passwd
chmod 600 /etc/postfix/sasl_passwd

postmap /etc/postfix/sasl_passwd

/etc/init.d/postfix restart

To test mail function:

mail -s test valid-email@whatever.com < /etc/hosts

You should then get an email from your Elastix box with subject "test".
