need help with e-mail validation

Boogy · March 24th, 2005, 08:12 PM

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>"
.Update
End With
strHTML = "<HTML>"
strHTML = strHTML & "<HEAD>"
strHTML = strHTML & "<BODY>"
strHTML = strHTML & "<b> This is the test HTML message body</b></br>"
strHTML = strHTML & ""
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
.fields.update
.Send
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

as fas as i know there is no way you can check if the email address is exists using ASP scripts, the only thing you can do just validate email address that users give is using valid email address formula.
example: you can check that your@your is not valid formula, and check that [email protected] is a valid formula.

There is really no way of checking if an email address is valid. What i do is use a regular exp to check for the obvious, . @ chars etc.. Then i do some error checking. Ie if err.number <> 0 then blah blah... You cant prevent people from entering a fake email address but you can help to prevent problems et
