Firstly, can someone point me to a link on setting up just
a plain Unix mailbox (no LDAP, no fanciful stuff). I know
how to use useradd to create a Unix account & nothing
more about getting it to be able to receive external emails.
Is saslauth needed for postfix to be able to receive mails?
I've deinstalled sendmail from my Linux postfix box &
reinstalled postfix.
Doing a find from root, there's only one copy of main.cf &
one copy of master.cf in the whole system.
On the postfix server, did a test:
# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
