I run postfix.
A lot of the mail I send out ends up in the bulk mail folders. Reason being for some reason when the mail arrives

[b](unknown sender)[/b] to me
To:(E-Mail address )
Date: 10-Dec-2006 19:56
Subject: hello there !!!

it arrives from [b]UNKNOWN SENDER[/b] and such messages are either filtered out or sent to the bulk mail folder.

Have run DNS Report which is fine including the reverese ptr address.
The php script itself is fine as when I send mail from my backup box on a separate windows xp computer with localhost set up on it using argosoft mail server the sender is clearly set up.

so it seems to be a problem with postfix and have throughly read and reread all the instructions and all seems ok.

when i run this command
> telnet hostname nor servname provided, or not known

I use the ipfw firewall. follow this link to see my firewall setting
(URL address blocked: See forum rules)=45174

What do i need to do so that when I send mail it does not arrive from UNKNOW SENDER

just tested telnet after disabling the ipfw firewall and still get the same response below

> telnet hostname nor servname provided, or not known

so must be something else

Runing freebsd 5.4

my hosts file

::1      localhost localhost
ipaddress one D9483
ipaddress one
ipaddress two D9483
ipaddress two
ipaddress three D9483
ipaddress three
ipaddress four D9483
ipaddress four

my host.conf file

# We have machines with multiple IP addresses.
multi on
# Check for IP address spoofing.
nospoof on

my resolv.conf file

nameserver ipaddress one
nameserver ipaddress two
nameserver ipaddress three
nameserver ipaddress four
