BSD Today: Using Postfix

(Other stories by Alan P. Laudicina)

"Tired of the sendmail's cryptic configuration, or do you find yourself complaining about its speed? Well then, postfix could be the MTA for you. The Postfix website defines postfix as a MTA which "attempts to provide an alternative to the widely-used Sendmail program." If it's speed and security you're looking for, Postfix is a very nominal choice for a MTA. According to the project's web site, Postfix is up to three times faster than its closest competitor, boasting the capability to send up to 1,000,000 different messages in a day."

"The MTA uses multiple layers of defense to protect the local system against intruders, as well as having the ability to run in a chroot jail. Installing on most operation systems is a trivial procedure, although in FreeBSD installation should be done differently to avoid the overwriting of the binaries when a make world is done. Another way to avoid this is to use a mail wrapper. (For more information on mail wrappers read the "Mail Wrappers" heading under the Installation section.)"

"All of the many configuration parameters can be found in the main.cf file, located in the ./conf directory in the postfix source. You need not change every parameter, as they are set to sensible defaults. Here are the details on some of the more important parameters, which will affect the performance of Postfix the most. Please note that if you change the main.cf file after installation, you must issue the postfix reload command. After installation, the main.cf file can be found in the /etc/postfix directory."
