determine Sendmail not to accept arbitrary "Mail From:" tag


hello,


i've just finished my first AUTH sendmail configuration, client cann
authentificate himself via LOGIN/PLAIN with TLS. I've noticed though
that sendmail doesn't pose any restraints regarding the mail from: tag.

lets say my domain is testmail.com, my loginname ist alex

aftet i succesfully authentificated myself, i cand send mails from arbitrary name @testmail.com... actually from
arbitrary name @ arbitrary domain

Am i missing something here ?

what i would like is: user authentificates -> he is allowed to send mail, but only with his address on it (!)
Thanks!

Regards,
Alex
