Email address syntax on contact creation

Hi,

I wanted to verify the validation that is in place when creating contacts.

There is this article in the support portal: https://support.oracle.com/epmos/faces/DocumentDisplay?id=1611010.1&parent=WIDGET_RECENTLY_VIEWED&sourceId= that partially explains it.

But is there an exact definition (& the syntax) of the server side validation of email addresses?

The validation used in the form is different in at least one thing: it accepts 1 character domain endings:

"test@test.c" is a valid email address according to the pattern implemented on forms, but it will actually not work, because then server side validation blocks it.
