+.SH DESCRIPTION
+.ad
+.fi
+The Postfix main.cf configuration file specifies parameters that
+control the operation of the Postfix mail system. Typically the
+file contains only a small subset of all parameters; parameters
+not specified are left at their default values.
+.PP
+The general format of the main.cf file is as follows:
+.IP \(bu
+Each logical line has the form "parameter = value".
+Whitespace around the "=" is ignored, as is whitespace at the
+end of a logical line.
+.IP \(bu
+Empty lines and whitespace-only lines are ignored, as are lines
+whose first non-whitespace character is a `#'.
+.IP \(bu
+A logical line starts with non-whitespace text. A line that starts
+with whitespace continues a logical line.
+.IP \(bu
+A parameter value may refer to other parameters.
+.RS
+.IP \(bu 
+The expressions "$name" and "${name}" are recursively replaced with
+the value of the named parameter. The parameter name must contain
+only characters from the set [a-zA-Z0-9_]. An undefined parameter
+value is replaced with the empty value.
+.IP \(bu
+The expressions "${name?value}" and "${name?{value}}" are replaced
+with "value" when "$name" is non-empty. The parameter name must
+contain only characters from the set [a-zA-Z0-9_]. These forms are
+supported with Postfix versions >= 2.2 and >= 3.0, respectively.
+.IP \(bu
+The expressions "${name:value}" and "${name:{value}}" are replaced
+with "value" when "$name" is empty. The parameter name must contain
+only characters from the set [a-zA-Z0-9_]. These forms are supported
+with Postfix versions >= 2.2 and >= 3.0, respectively.
+.IP \(bu
+The expression "${name?{value1}:{value2}}" is replaced with "value1"
+when "$name" is non-empty, and with "value2" when "$name" is empty.
+The "{}" is required for "value1", optional for "value2". The
+parameter name must contain only characters from the set [a-zA-Z0-9_].
+This form is supported with Postfix versions >= 3.0.
+.IP \(bu
+The first item inside "${...}" may be a relational expression of the
+form: "{value3} == {value4}". Besides the "==" (equality) operator
+Postfix supports "!=" (inequality), "<", "<=", ">=", and ">". The
+comparison is numerical when both operands are all digits, otherwise
+the comparison is lexicographical. These forms are supported with
+Postfix versions >= 3.0.
+.IP \(bu
+Each "value" is subject to recursive named parameter and relational
+expression evaluation, except where noted.
+.IP \(bu
+Whitespace before or after each "{value}" is ignored.
+.IP \(bu
+Specify "$$" to produce a single "$" character.
+.IP \(bu
+The legacy form "$(...)" is equivalent to the preferred form "${...}".
+.RE
+.IP \(bu
+When the same parameter is defined multiple times, only the last
+instance is remembered.
+.IP \(bu
+Otherwise, the order of main.cf parameter definitions does not matter.
+.PP
+The remainder of this document is a description of all Postfix
+configuration parameters. Default values are shown after the 
+parameter name in parentheses, and can be looked up with the
+"\fBpostconf \-d\fR" command. 
+.PP
+Note: this is not an invitation to make changes to Postfix
+configuration parameters. Unnecessary changes can impair the
+operation of the mail system.
