FetchSPF

FetchSPF is an ActiveX component that returns SPF-1 IP Numbers

Description

SPF establishes a policy framework and a sender authentication scheme that verifies the identity of email servers (domains) for incoming messages. The Control willreturn all the IP numbers associated with a domain which is using SPF Records.

Methods

Fetch

Returns a string with all the IP numbers separated by a ‘\|’. It is recursive and will display duplicate IP’s. If there are no SPFrecords a blank string is returned.
object. fetch(Top level domain,DNS)
Top level domain	String	i.e hotmail.com
DNS	String	DNS to use for check. e.g 127.0.0.1
Returns	String

Parameters

SenderIP

Set to the email senders IP. Used in evaluating PTR records
object.Senderip
Senderip	String
Returns	String

Failtype

Set to 0,1 or 2. Defines the ALL types. The all type terminates processing. It is normally present in the form -all to signify that if processing reaches this point without a prior match the result will be fail. But if you are not sure that the tests are conclusive you could use ?all which would allow mail to be accepted even if all previous checks failed. 0 = -ALL. Pass Only Hard Fail 1 = ~ALL. Fail Soft and Hard 2 = ?ALL .Ignore All function
object.failtype
Failtype	Integer
Returns	Integer

Visual Basic

Dim fetchspf As Object

fetchspf = CreateObject(”fetchspf.spfread”)

fetchspf.senderip = “216.113.167.215″
fetchspf.failtype = 0

RichTextBox1.Text = fetchspf.fetch(”ebay.co.uk”,”127.0.0.1″)

Returns e.g
66.135.195.180|216.113.167.215|66.135.195.181|66.135.195.181|………

FoxPro

fetchspf = Createobject(’fetchspf.spfread’)

fetchspf.senderip=Alltrim(”216.113.167.215″)
fetchspf.failtype = 0

thisform.edit1.Value = fetchspf.Fetch(”ebay.co.uk”,”127.0.0.1″)

Returns e.g
66.135.195.180|216.113.167.215|66.135.195.181|66.135.195.181|………

Delphi

var

fetchspf : olevariant;
begin

Try

fetchspf := CREATEoleOBJECT(’fetchspf.spfread’);

fetchspf.senderip :=trim(’216.113.167.215′);

fetchspf.failtype = 0

memo1.Text:= fetchspf.Fetch(’ebay.co.uk’,'127.0.0.1′);

finally

fetchspf := VarNull;

end;

Returns e.g
