Detecting valid email format F4

[JGL]

Ok, I need to detct that an email address a user puts in a form field is

formatted properly.


Minimum formatting would be:

xx [dot] xx

In otherwords, it *must* contain a '@' and a '.', plus it must have

*atleast* 1 character before the '@' and *atleast* 1 character after the '@'

or before the '.', plus *atleast* two characters after the '.'


Anyone one do this before and have a quick F4 solution that checks before

the form is submitted? I need this cause the cgi mailer I'm using won't

submit without this parameter.


I could just use a valid e-mail addy as the'from' field but would like to

make it convenient for my client to simply hit reply when he receives a cgi

generated mail.


Thanks for any insight . . . .
