Delphi Example

Validate Email Address Syntax

Regular expression can be used to validate if an email address is in correct format. For example: you can use this "^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$" pattern to verify if the email address has valid format.

Test Email Address

Even the email address has a valid format, it doesn't mean the email address is existed in real world. TestEmailAddr method can be used to test if the email address is valid.

// The following example codes demonstrate testing email address using MX DNS lookup
// To get full sample projects, please download and install EASendMail on your machine.
// To run it correctly, please change SMTP server, user, password, sender, recipient value to yours

Code:

Unit Unit1; 

Interface 

Uses 
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, 
  Dialogs, StdCtrls, EASendMailObjLib_TLB; // add EASendMail Unit 

Type 
  TForm1 = Class(TForm) 
    Button1: TButton; 
    Procedure Button1Click(Sender: TObject); 
  private 
    { Private declarations } 
  public 
    { Public declarations } 
  End; 

Var 
  Form1: TForm1; 

Implementation 

{$R *.dfm} 

Procedure TForm1.Button1Click(Sender: TObject); 
Var 
  oSmtp : TMail; 
Begin 
  oSmtp := TMail.Create(Application); 
  oSmtp.LicenseCode := 'TryIt'; 

  // Set your sender email address
  oSmtp.FromAddr := 'test@emailarchitect.net'; 

  // Add recipient email address
  oSmtp.AddRecipientEx( 'support@emailarchitect.net', 0); 

  // Do not set SMTP server address
  oSmtp.ServerAddr := ''; 

  ShowMessage( 'start to test email address ...' ); 

  If oSmtp.TestEmailAddr() = 0 Then 
    ShowMessage( 'email address was verified!' ) 
  Else 
    ShowMessage( 'failed to test email address with the following error: ' 
    + oSmtp.GetLastErrDescription()); 

End; 

End.

Hi, You need to copy EASendMailObj.dll to your machine, then use regsvr32 "c:\my folder\EASendMailObj.dll" to register it as activex object. Please run the command as administrator in vista or later windows version.
