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?

Yes, I edited it. hostname was just the name of the host as
given by Unix command 'uname -n' or `hostname`

Noel, so do I append "-v" or "-D" on the smtpd line in master.cf ?
Or are you referring to "strace -p postfix_process_pid" ?

So do I remove "-v" & use "-D" in master.cf, restart postfix &
send test emails ?

I'm sending from external Outlook/Exchange to my SMTP postfix.
Sending outgoing emails from this dovecot/postfix server is Ok
(ie emails received at destination) but incoming mails keep
getting the logs below :

Sorry for the lack of info in earlier post.
Think the main issue is I can't even start up postfix :

But gmail doesn't allow/accept brackets (square or round brackets)

Thanks very much Victor & Jeroen.
As I'm a newbie/beginner, guess I'll stick to "sender access map"
& see if there are many spoofed emails.
I have a lot to learn from this list.

So is it right to say that though I want only a small handful of

it could be email gateways (or "mail relay servers" ??) that are

Does anyone has any sample php scripts which emulate a POP3
client going into an Exchange server to download mails & then clear
away mails from the Exchange server's mailbox?
Care to share?

when disk got corrupted/crashed (even mirror disks failed us in
our environment), is there sort of hot backups for postfix queues?

If there's a hard disk crash or corruption of /var/spool/postfix/...,
can we restore from tapes the /var partition & is there any
special recovery of postfix needed?
