Compilation / Installation

To build SmtpRC please run "make" in the package directory. This will build the package and create the binary "smtprc". To install the package, please run "make install".

By Default, the binary will be installed into /usr/local/bin/, configuration files will be installed under /usr/local/etc/smtprc/ and all documentation files will be installed under /usr/local/share/doc/smtprc/. Please see below for a full list of installed files.


Using Smtprc

SmtpRC can be run by specifying options on the command line, or by configuring an "auto configuration" file and letting SmtpRC parse the options from there. The latter is recommended.

When SmtpRC is installed, a example "auto configuration" file is installed in "/usr/local/etc/smtprc/auto.conf". Edit this file, changing the values to suit your specific network requirements and run smtprc with the following option (a full list of options
is detailed below):

"/usr/local/bin/smtprc -j /usr/local/etc/smtprc/auto.conf"

To be sure that a mailserver relays third-party email, SmtpRC will attempt to relay mail to an address specified. It is recommended that this address is a mailbox on the local machine that is being used to run SmtpRC - pop support is a planned feature, but for now, SmtpRC only supports checking local mailboxes (mbox and Maildir). Create a new user account (smtprc), specify the email address for this account, and the local mailbox (on the command line or in the "auto configuration" file), and SmtpRC will attempt to relay emails to this address and check for recieved emails after scanning.

There is also a GUI interface to smtprc (gsmtprc) that is installed in /usr/local/bin. This requires Perl Tk to run.

What's New in This Release:

?Fixes a race condition between the master and reaper threads.

Supported Operating System:

Probably All
