It seems to be normal behaviour, but when using jquery's validate
plugin my client was not happy the a single domain suffix character
was enough to clear the valid email error. ie; tes...@googlemail.c
would validate.
To ensure that at least 2 characters had to be entered into the field
to validate I changed the email function to the following;
email: function(value, element) {

return this.optional(element) ||
/^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?
\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\
$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])
+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b
\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-

i.test(value);
},
I'm no expert at regex but this worked for me.
Thanks,
