but then again you get clever guys on the net (whoever programs VB
must be...) giving examples of faulty email address valildation:

Server Side Email Addresses Validation using VBScript
by . << I would have reported the author if it had been there!

[...]
if InStr("abcdefghijklmnopqrstuvwxyz_-.", c) <= 0 and not IsNumeric(c) then
      isitvalid = false
      exit function
[...]


and again:

If the value of variable "c" is not a substring of string
"abcdefghijklmnopqrstuvwxyz_-." (all valid characters in an email
address), then the email address passed is invalid and [...]

I think the invalid is the author of that piece of code, he and his
progenie are responsible for all the times that I tried to enter a
user+something local part in a form's email box.

You can bet I will register to that site to post a comment and hurl
abuse at this anonymous "coder".

[ah, this is more like me!]
