i can't find a good code to check if e-mail exists. im trying to do this with cdo. maybe someone could sugest some source?
or maybe could help to make it...
here is what im trying to do

Dim iMsg
Dim iConf
Dim Flds
Dim strHTML
set imsg = createobject("cdo.message")
set iconf = createobject("cdo.configuration")
Set Flds = iconf.Fields
With Flds
.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "<SMTP Server>"
End With
strHTML = "<HTML>"
strHTML = strHTML & "<HEAD>"
strHTML = strHTML & "<BODY>"
strHTML = strHTML & "<b> This is the test HTML message body</b></br>"
strHTML = strHTML & "<hr>"
strHTML = strHTML & "This another section of the message...</BR>"
strHTML = strHTML & "</BODY>"
strHTML = strHTML & "</HTML>"
With iMsg Set
.Configuration = iConf
.To = "<valid e-mail address>"
.From = "<valid e-mail address>"
.Subject = "This is a test CDOSYS message (Setting DSN options)"
.HTMLBody = strHTML
.fields("urn:schemas:mailheader:disposition-notification-to") = "<valid e-mail address>"
.fields("urn:schemas:mailheader:return-receipt-to") = "<valid e-mail address>"
.DSNOptions = cdoDSNSuccessFailOrDelay
.DSNOptions = 14
End With

i'm sending message to the e-mail i want to check for validation. and i can get confirmation that mail was sent succesfuly. but the problem is that i get it by mail. i want to check if e-mail is valid in the source code. if its possible

thank you

There is no way to check that a email address exists in ASP. The only thing you could do is a "whois" on the domain to make sure it is real, but that is about all you can do.


I can never actually needed to code this but you could probably take a look at this script and recode it so check for the email domain of the user and make sure it is valid.
