Hi all -
I want to set up an SMTP / POP3 server on RH Linux 8.0.
I have POSTFIX and the IMAP packages installed. As I am
perusing the documentation for both, I have some questions...
My setup requires that my host will accept mail for three
different domains. I have configured DNS for my domain(s)
so that myhost.domainA.com is the MX for domainA.com,
domainB.com, and domainC.com.
My questions are:
When I am creating email addresses/mailboxes for users, do they have to
be actual users that I create on the Linux host, or can I just
create phantom mailboxes?
Can I tell POSTFIX that it can send mail for pop3 clients
without creating an open relay?
Thanks in advance for sharing your advice / experience -
