Variables are not expanded inside single quotes. Things like $LOG_FILE will expand on the remote server instead, probably to nothing.

mail::spf::macrostring
Mail::SPF::MacroString(3) User Contributed Perl Documentation Mail::SPF::MacroString(3)
NAME
Mail::SPF::MacroString - SPF record macro string class
SYNOPSIS
Providing the expansion context early
use Mail::SPF::MacroString;
my $macrostring = Mail::SPF::MacroString->new(
text => '%{ir}.%{v}._spf.%{d2}',
server => $server,
request => $request
);
my $expanded = $macrostring->expand;
Providing the expansion context late
use Mail::SPF::MacroString;
my $macrostring = Mail::SPF::MacroString->new(
text => '%{ir}.%{v}._spf.%{d2}'
);
my $expanded1 = $macrostring->expand($server, $request1);
$macrostring->context($server, $request2);
my $expanded2 = $macrostring->expand;
DESCRIPTION
An object of class Mail::SPF::MacroString represents a macro string that can be expanded to a plain string in the context of an SPF
request.
Constructor
The following constructor is provided:
new(%options): returns Mail::SPF::MacroString
Creates a new SPF record macro string object.
%options is a list of key/value pairs representing any of the following options:
text
Required. The unexpanded text of the new macro string.
server
The Mail::SPF::Server object that is to be used when expanding the macro string. A server object need not be attached statically
to the macro string; it can be specified dynamically when calling the "expand" method.
request
The Mail::SPF::Request object that is to be used when expanding the macro string. A request object need not be attached statically
to the macro string; it can be specified dynamically when calling the "expand" method.
is_explanation
A boolean denoting whether the macro string is an explanation string obtained via an "exp" modifier. If true, the "c", "r", and
"t" macros may appear in the macro string, otherwise they may not, and if they do, a Mail::SPF::EInvalidMacro exception will be
thrown when the macro string is expanded. Defaults to false.
Instance methods
The following instance methods are provided:
text: returns string
Returns the unexpanded text of the macro string.
context($server, $request): throws Mail::SPF::EOptionRequired
Attaches the given Mail::SPF::Server and Mail::SPF::Request objects as the context for the macro string.
expand: returns string; throws Mail::SPF::EMacroExpansionCtxRequired, Mail::SPF::EInvalidMacroString, Mail::SPF::Result::PermError
expand($server, $request): returns string; throws Mail::SPF::EMacroExpansionCtxRequired, Mail::SPF::EInvalidMacroString,
Mail::SPF::Result::PermError
Expands the text of the macro string using either the context specified through an earlier call to the "context()" method, or the given
context, and returns the resulting string. See RFC 4408, 8, for how macros are expanded.
is_explanation: returns boolean
Returns true if the macro string is an explanation string obtained via an "exp" modifier. See the description of the "new"
constructor's "is_explanation" option.
stringify: returns string
Returns the expanded text of the macro string if a context is attached to the object. Returns the unexpanded text otherwise. You can
simply use a Mail::SPF::MacroString object as a string for the same effect, see "OVERLOADING".
OVERLOADING
If a Mail::SPF::MacroString object is used as a string, the "stringify" method is used to convert the object into a string.
