6 Mail::SPF::Record - Abstract base class for SPF records
7
9 Creating a record from a string
10 use Mail::SPF::v1::Record;
11
12 my $record = Mail::SPF::v1::Record->new_from_string("v=spf1 a mx -all");
13
14 Creating a record synthetically
15 use Mail::SPF::v2::Record;
16
17 my $record = Mail::SPF::v2::Record->new(
18 scopes => ['mfrom', 'pra'],
19 terms => [
20 Mail::SPF::Mech::A->new(),
21 Mail::SPF::Mech::MX->new(),
22 Mail::SPF::Mech::All->new(qualifier => '-')
23 ],
24 global_mods => [
25 Mail::SPF::Mod::Exp->new(domain_spec => 'spf-exp.example.com')
26 ]
27 );
28
30 Mail::SPF::Record is an abstract base class for SPF records. It cannot
31 be instantiated directly. Create an instance of a concrete sub-class
32 instead.
33
34 Constructor
35 The following constructors are provided:
36
37 new(%options): returns Mail::SPF::Record
38 Creates a new SPF record object.
39
40 %options is a list of key/value pairs representing any of the
41 following options:
42
43 text
44 A string denoting the unparsed text of the record.
45
46 scopes
47 A reference to an array of strings denoting the scopes that are
48 covered by the record (see the description of the "scope"
49 option of Mail::SPF::Request's "new" constructor).
50
51 terms
52 A reference to an array of Mail::SPF::Term (i.e.
53 Mail::SPF::Mech or Mail::SPF::Mod) objects that make up the
54 record. Mail::SPF::GlobalMod objects must not be included
55 here, but should be specified using the "global_mods" option
56 instead.
57
58 global_mods
59 A reference to an array of Mail::SPF::GlobalMod objects that
60 are global modifiers of the record.
61
62 new_from_string($text, %options): returns Mail::SPF::Record; throws
63 Mail::SPF::ENothingToParse, Mail::SPF::EInvalidRecordVersion,
64 Mail::SPF::ESyntaxError
65 Creates a new SPF record object by parsing the string and any
66 options given.
67
68 Class methods
69 The following class methods are provided:
70
71 version_tag_pattern: returns Regexp
72 Abstract. Returns a regular expression that matches a legal
73 version tag.
74
75 This method is abstract and must be implemented by sub-classes of
76 Mail::SPF::Record.
77
78 default_qualifier: returns string
79 Returns the default qualifier, i.e. '+'.
80
81 results_by_qualifier: returns hash of string
82 Returns a reference to a hash that maps qualifiers to result codes
83 as follows:
84
85 Qualifier | Result code
86 -----------+-------------
87 + | pass
88 - | fail
89 ~ | softfail
90 ? | neutral
91
92 Instance methods
93 The following instance methods are provided:
94
95 text: returns string; throws Mail::SPF::ENoUnparsedText
96 Returns the unparsed text of the record. Throws a
97 Mail::SPF::ENoUnparsedText exception if the record was created
98 synthetically instead of being parsed, and no text was provided.
99
100 version_tag: returns string
101 Abstract. Returns the version tag of the record.
102
103 This method is abstract and must be implemented by sub-classes of
104 Mail::SPF::Record.
105
106 scopes: returns list of string
107 Returns a list of the scopes that are covered by the record. See
108 the description of the "new" constructor's "scopes" option.
109
110 terms: returns list of Mail::SPF::Term
111 Returns a list of the terms that make up the record, excluding any
112 global modifiers, which are returned by the "global_mods" method.
113 See the description of the "new" constructor's "terms" option.
114
115 global_mods: returns list of Mail::SPF::GlobalMod
116 Returns a list of the global modifiers of the record, ordered
117 ascending by modifier precedence. See the description of the "new"
118 constructor's "global_mods" option.
119
120 global_mod($mod_name): returns Mail::SPF::GlobalMod
121 Returns the global modifier of the given name if it is present in
122 the record. Returns undef otherwise. Use this method if you wish
123 to retrieve a specific global modifier as opposed to getting all of
124 them.
125
126 stringify: returns string
127 Returns the record's version tag and terms (including the global
128 modifiers) formatted as a string. You can simply use a
129 Mail::SPF::Record object as a string for the same effect, see
130 "OVERLOADING".
131
132 eval($server, $request): throws Mail::SPF::Result
133 Evaluates the SPF record in the context of the request parameters
134 represented by the given Mail::SPF::Request object. The given
135 Mail::SPF::Server object is used for performing DNS look-ups.
136 Throws a Mail::SPF::Result object matching the outcome of the
137 evaluation; see Mail::SPF::Result. See RFC 4408, 4.6 and 4.7, for
138 the exact algorithm used.
139
141 If a Mail::SPF::Record object is used as a string, the "stringify"
142 method is used to convert the object into a string.
