Enable Outgoing Emails (view source)

{{MessageBox|backgroundcolor = #faa|image =Warning.png|heading =WARNING|message = This is recommended only for advanced users, proceed with caution.}}Here's how to enable outgoing emails on your Amahi server.
To begin with, [[Open Terminal as root|As '''root''' user]]do the following:
SMTP_SERVER=your_isp_smtp_server
yum -y install sendmail-cf m4
sed -ie "s/.*SMART_HOST.*/define(\`SMART_HOST', \`$SMTP_SERVER')dnl/" sendmail.mc
make
chkconfig sendmail onservice sendmail restart}}</pre>
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 connect to the SMTP server using port 587 (TLS/STARTTLS), you'll need to do this too:
cd /etc/mail
sed -ie "s/\(.*SMART_HOST.*\)/\1\ndefine(\`RELAY_MAILER_ARGS', \`TCP \$h 587')dnl\ndefine(\`ESMTP_MAILER_ARGS', \`TCP \$h 587')dnl/" sendmail.mc
make
service sendmail restart
If you want to use another port than 587, change that number in the above command (it's there twice), before executing it. If you already executed it, edit the sendmail.mc file, and search for 587 - it should appear there twice - change both.
service sendmail restart

Sendmail is picky about the quotation marks: when I first pasted them, they were wrong and gave me a syntax error.
