Mail format control

A quick way (though not fully correct) to check the conditions you listed would be to use the following expression:

= with(
 local!at: find("@", ri!email),
 local!dot: find(".", ri!email, local!at),
 and(local!at>1, local!dot>local!at+1)
)

You'd need to add logic to disallow a@b..c and other invalid inputs.
