PortSystem 1.0

Version: 2.5.5
Category: mail
Maintainers: nomaintainer
Description: Fast and robust mail transfer agent
Long Description: Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail-compatible enough to not upset existing users. It also offers QMQP and VERP support to let Postfix act as delivery daemon for ezmlm-idx.

ui_msg "\n
To get postfix working, you need to copy the sample configuration
files and edit them (${prefix}/etc/postfix/*.sample). You may also
want to turn off Apple's built-in MTA. For example, on 10.4:

-Delete or rename /System/Library/LaunchDaemons/org.postfix.master.plist
-Replace the built-in sendmail file with a symlink to MacPorts' own:
sudo mv /usr/sbin/sendmail /usr/sbin/sendmail.org
ln -s ${prefix}/sbin/sendmail /usr/sbin/sendmail

NOTE: Apple OS updates could upgrade the built-in Postfix and overwrite the
symlink, so the symlink mught have to be recreated.

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/postfix
%  sudo port install postfix  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching postfix
--->  Verifying checksum for postfix
--->  Extracting postfix
--->  Configuring postfix
--->  Building postfix with target all

--->  Staging postfix into destroot

--->  Installing postfix

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using postfix with these commands:

%  man postfix
%  apropos postfix
%  which postfix
%  locate postfix
