     Validating an email address is a big headache to both the web and stand alone app developers. Especially when the e-mail is used as the handle or key to your transactions, its structure becomes of importance and has to be properly entered. Unfortunately developing a module or an application to solve this problem is not without its own set of problems ....besides having to spend valuable time in combining and interpreting the validations. As a developer, I faced this problem more than once and decided to find a permanent solution...and what better way than to develop a COM component!! and make it universally perusable! Yes, you now have a powerful piece of component(with its source code) at your disposal. This COM not only comes as a boon(because of its inherent quality of being a COM and being multiusable), but also a great time saver . I'm sure you'll find this component worthy, as has many other developers in my organisation(yes!! its widely used in my company :)). I have covered all aspects of email validations here ...so when you enter an email address for verification, you are sure it'll be verified!! I have also added the DLL along with the ZIP :)

Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com

Here's a simple one:

https://www.emailarchitect.net/easendmail/ex/b/11.aspx

' 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

Private Sub btnSendMail_Click()

Dim oSmtp As New EASendMailObjLib.Mail
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 = ""

MsgBox "start to test email address..."

If oSmtp.TestEmailAddr() = 0 Then
MsgBox "email address was verified!"
Else
MsgBox "failed to test email address with the following error:" & oSmtp.GetLastErrDescription()
End If

End Sub
