The Exim FAQ

This is the FAQ for the Exim Mail Transfer Agent. Many thanks to the many people who provided the original information. This file would be amazingly cluttered if I tried to list them all. Suggestions for corrections, improvements, and additions are always welcome.

This version of the FAQ applies to Exim 4.00 and later releases. It has been extensively revised, and material that was relevant only to earlier releases has been removed. As this caused some whole sections to disappear, I've taken the opportunity to re-arrange the sections and renumber everything except the configuration samples.

References of the form Cnnn, Fnnn, and Lnnn are to the sample configuration, filter, and local_scan() files. These are hyperlinked from the HTML version of this FAQ. They can also be found in the separately distributed directory called config.samples. The primary location is

ftp://ftp.csx.cam.ac.uk/pub/software/email/exim/exim4/config.samples.tar.gz ftp://ftp.csx.cam.ac.uk/pub/software/email/exim/exim4/config.samples.tar.bz2

There are brief descriptions of these files at the end of this document.
