[Exim] sender verify problem

I'm running Debian with exim 4.40. I don't know if is more a problem
about the distribution, but my

require verify = sender

is not working well. I run exim4 -bh and I get this

**** SMTP testing session as if from host 123.123.123.123
**** but without any ident (RFC 1413) callback.
**** This is not for real!

It seems like it just test for a valid dns server, but not for a valid
user on a valid domain. Is the verify = sender condition implemented
only on the source or is there any way I can modify the behaibior?
