2.6. Configuring Outbound Email

Configuring RT to send mail consists of a few steps. First of all, make sure that the server has a working MTA (Mail Transfer Agent).

Common MTAs include sendmail (http://www.sendmail.org/), postfix (http://www.postfix.org/), and qmail (http://cr.yp.to/qmail.html). Most Unix-based operating systems ship with at least one of these available by default (Linux distributions have almost all of them available, in fact). Installing and configuring the MTA is beyond the scope of this book, but the vendors' web sites all provide detailed installation and configuration instructions.

Once you have the MTA installed and set up to send mail, you need to tell RT to use it. Look in the RT_Config.pm file, and copy the following lines to RT_SiteConfig.pm:

     Set($SendmailPath , "/usr/sbin/sendmail");     Set($SendmailArguments , "-oi -t"); 

Since it's the traditional location for sendmail, /usr/sbin/sendmail will usually work. Most other MTAs respect this tradition through compatibility wrappers. If /usr/sbin/sendmail does not exist, try /usr/lib/sendmail.
