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
