Hi all,
As part of my mail system I am using postgrey.
I am running Centos 5.2, MailScanner latest version with postfix and
spamassassin
When stuff is stopped at the gate (so to speek) i.e. it doesn't even get
into the the system is there a log kept of this?
I thought it might be in the mail

Hi All,
We are doing an upgrade on the machine that holds the postboxes
(mailenable) during the upgrade the server will need to be rebooted
which renders the boxes unreachable.
This causes a 550 error to be sent back to our spam catching server

Robert, thanks
what I'm after is, should I set banner to match real host name;
or, can I get away with using my own host name ;
will it cause problems down the road ?
I'm migrating virtual mail domain/users to new Postfix server,
new server setup and working, I'm altering MX to point to the new server;
I want the 'old' server to forward any new traffic over to the new server,

transport_maps = static:smtp:
can anyone point me to any howtos if such exist: on setting up a head
office/branch office mail servers (is that correct way to name it?)
we have a mail server in Australia, the office is split up between AUS and
Asia, most of the users are in Asia, so emails from physically adjacent
users travel

the passwd-file is to allow for

one reverse pointer will match. My mail does not get bounced for that.
And before someone posts you can have more than one reverse pointer per IP the
VPS (Digital Ocean) says it can't be done.
