Response Event

Fired for each MailServer accepting email for the domain.

Syntax

typedef void __fastcall (__closure *TipwMXResponseEvent)(System::TObject* Sender, TipwMXResponseEventParams *e);

__property TipwMXResponseEvent OnResponse = {read=FOnResponse, write=FOnResponse};

typedef struct {
     int RequestId;
     String Domain;
     String MailServer;
     int Precedence;
     int TimeToLive;
     int StatusCode;
     String Description;
     bool Authoritative;
} TipwMXResponseEventParams;

Remarks

A Response event is fired for each mail server handling email for the requested domain. The RequestId parameter identifies the request and equals the value of RequestId property right before the Resolve method is called. MailServer is the name of the server handling email for the requested Domain. A lower Precedence value should be preferred. The TimeToLive parameter gives the validity time in seconds before the DNSServer should be queried again.

Possible values for the StatusCode and Description parameters are:

StatusCode	Description
0	Ok
1	Format error
2	Server failure
3	Name error
4	Not implemented
5	Refused

After the last Response event is fired, the component sets the MailServer and Status properties to the best MailServer and the error or success code respectively.
