Enable Outgoing Emails

Here's how to enable outgoing emails on your Amahi server.

As root:

 SMTP_SERVER=your_isp_smtp_server
 yum -y install sendmail-cf m4
 cd /etc/mail
 sed -ie "s/.*SMART_HOST.*/define(\`SMART_HOST', \`$SMTP_SERVER')dnl/" sendmail.mc
 m4 sendmail.mc > sendmail.cf
 service sendmail restart

Make sure to replace your_isp_smtp_server on the first line with the hostname or IP address of your ISP SMTP server.

If you need to provide a username and password to use the SMTP server, you'll need to do this too:

 SMTP_SERVER=your_isp_smtp_server
 USERNAME=your_smtp_username
 PASSWORD=your_smtp_password
 cd /etc/mail
 echo "AuthInfo:$SMTP_SERVER \"U:$USERNAME\" \"P:$PASSWORD\" \"M:PLAIN\"" >> access
 makemap hash access < access
 service sendmail restart
