VC++ ExampleValidate 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
#include "stdafx.h"
#include "easendmailobj.tlh"
using namespace EASendMailObjLib;
int _tmain(int argc, _TCHAR* argv[])
{
::CoInitialize( NULL );
IMailPtr oSmtp = NULL;
oSmtp.CreateInstance( "EASendMailObj.Mail");
oSmtp->LicenseCode = _T("TryIt");
// Set your sender email address
oSmtp->FromAddr = _T("test@emailarchitect.net");
// Add recipient email address
oSmtp->AddRecipientEx( _T("support@emailarchitect.net"), 0 );
// Do not set SMTP server address
oSmtp->ServerAddr = _T("");
_tprintf(_T("Start to test email address...\r\n" ));
if( oSmtp->TestEmailAddr() == 0 )
{
_tprintf( _T("email was verified!\r\n"));
}
else
{
_tprintf( _T("failed to test email address with the following error: %s\r\n"),
(const TCHAR*)oSmtp->GetLastErrDescription());
}
if( oSmtp != NULL )
oSmtp.Release();
return 0;
}
