The hot stickers of 9CBS users v_object provide solutions, which are summarized as follows:
1, use web services
A, add a web reference. Open VS, right click on the project manager, select Add Web Service, enter the URL address address in the web reference window from the pop-up:
http://ws.cdyne.com/emailverify/ev.asmx, then press "Go to" to find a service called EV, using the default reference: com.cdyne.ws, point "Add Web Reference" Button, complete the addition process.
B, application.
Define an object Myev:
Dim myev as new com.cdyne.ws.ev
With EV's Verifyemail method, the parameter is the email to verify. If the address exists "Mail Server Will Accept Email", it returns "Email Domail Not Found", or "User Not Found"
Label1.text = myev.verifyemail (txtemail.text.tostring) .Responsetext
2, write this RCPT to this RCPT TO, I will understand the version of the moderator.
I am not the moderator, I don't understand, but the landlord has not detailed, so I can only continue to pay attention!
