Sendmail and system users
I've been trying to figure out how to limit particular users from
getting non-local mail. I'm not sure of some terminologies that I might
be trying to describe so please bare with me.
For example, users bin, sys, mail, sync, games are non-interactive user
accounts and I pretty sure I don't want them to get email from the
outside world (correct me if i'm wrong). I'd like to some how restrict
these users. I'm probably am not providing enough information but
here's my sendmail.mc file.
Thanks for anyone's help in advance.
