Get this message from one of my users who tried to e-mail some one

Client host rejected: Please do not SPAM, use your official mailgateway>

i have read post posts on the is subject about it being a reverse lookup problem.

But i dont know where to start

here is how every thing is set up

I have a mail server and a file server

Mail server on 196.168.0.3
file server on 196.168.0.5
Gateway on 196.168.0.52

Out side Leased line through firwall 142.142.142.142

The mail server is configured to @yourhere.com
This Email address is only used if the main mail server in Houston fails.(we are in the UK)
We all have mail boxes in Houston that are forwared to our mail server the address being @ouraddress.com
Houston mail server is configured to @ouraddress.com
We send by default smtp mail  on (our Uk server) from the address @ouraddress.com

did a nslookup

Default server points to file server with correct lan ip address

set type = ptr
Inputted Internet ip address 142.142.142.142
Got Non-authortive answer
11.11.11.11..in-addr.arpa     name =  no-dns-yet.co.uk

All the names and numbers have been made up

how do i set up my reverse look ups and where


Thanks in advance Mark

Reverse DNS is done on your PTR records.  Place the reverse entry in your A record of your zonefile: 1 PTR mail.yourhere.com

Whoever handles your dns records can do this for you.  Its a common request.

so from the example above 142.142.142.142 needs a ptr records
most likely.  who handles your dns server(s)?  They should be able to do this for you easily.
