# This is a default configuration file which will operate correctly in

|
# uncomplicated installations. Please see the manual for a complete list
|
|
# of all the runtime configuration options that can be included in a
|
|
# configuration file. There are many more than are mentioned here. The
|
|
# manual is in the file doc/spec.txt in the Exim distribution as a plain
|
|
# ASCII file. Other formats (PostScript, Texinfo, HTML, PDF) are available
|
|
# from the Exim ftp sites. The manual is also online via the Exim web sites.
|
|
|
|
|
|
# This file is divided into several parts, all but the last of which are
|
|
# terminated by a line containing the word "end". The parts must appear
|
|
# in the correct order, and all must be present (even if some of them are

|
# in fact empty). Blank lines, and lines starting with # are ignored.
