Server-Side e-mail Validation with ASP.

Joco Vieira

This one is very simple….
but there is always someone trying to reach this code…. I hope you understand
the code.

1. First I have created a variable that at the end could give me if the
validation is ok or not ‘goby’.

2. So, I have used the
function InStr that gives me True Or False about any character inside
a String.

This one is very simple…. but there is always someone trying to reach this code…. I hope you understand the code.

3. So here is the code, use
it as you want

Dim goby
goby = 0 //Starting the goby string
    I f Len(session(“emailfrom”))
     else
        If InStr(1, session(“emailfrom”),
“@”, 1)
            
goby = 1
                Else
                   If
InStr(1,session(“emailfrom”), “.”, 1)
                      
goby = 1
                   End
If
        End If
End If
If goby 0 then // well , if goby 0 then something
must be wrong
     response.write “Bad E-Mail…”
End If
