Hi my organisation needs to control sending of mail to the internet.
I am using Sendmail::Milter on a FC1, I need to allow only a few local users to send mail to the internet, remaining users should be allowed to send mail on the intranet only.
should be able to send mail to, say email@example.com
, however when firstname.lastname@example.org
sends to email@example.com
it should give him an error.
However when tom sends to another local user it should go through.
I am using outlook as my mailing clients on the lan.
How do i do this using senmail /sendmail::milter. Or is there another method??
