>> using the console provided by your ISP.
Do you mean the console cable ?? those use to connect the cisco router (RJ-45) to VGA ??
>> Call up your ISP support (the best deal) for helping you out.
What do you think the information will needed from the ISP ?? the server IP address (203.120.27.227) ??
Is that the ISP will create & configure the PTR Records in their ISP side (or the customer side) ?? (Because so far the ISP does not provide any things to the customer) .....

Okay, let's go back to the beginning when you setup your SBS server...
1) Who supplied you with the static IP address you are currently using for the server?
2) Do you have a registered domain name for your site -- i.e. for accepting e-mail, etc?

In the meantime, it might be helpful to ask the people at the other end to make an exception for your server in the rDNS lookup. So at least the email keeps flowing. This should be possible somwhere in the recipient's server.

ya .... the company have their own website : www.alliancefrancaise.org.sg but is not hosting in their own server .... could be third party ...... but when i go to http://www.dnsstuff.com/ .... then key in their domain alliancefrancaise.org.sg and it shows 1 blacklisted .... could it be the cause of the mail get bounced back as well ?? cause currently the company using outlook with the format like : irene@alliancefrancaise.or

The static IP you mention in here is not the internal IP (192.168.10.250) is it ?? Or normally you guys named the static IP is for the IP from internet (203.120.27.227) ???

It shows 203.120.27.227 ..... then what does that mean for the result in www.dnsstuff.com ?? And i saw a sticker on the router from the ISP listed 203.120.27.224/22 ...... does that mean the ISP they set up wrongly ??
ASKER
Thanks guys ..... finally the ISP provider solved it out by asking me to provide the server name to them .... they say will add in a PTR record. (Does anyone know the steps ?? Is that Start > Programs > Administrative Tools > DNS > under Reverse lookup zone > right click > new PTR > then key in the host name (afexch.afsgp.local) ?? that is it ??)
ASKER
ok .... lets make it simple, does that mean Reverse DNS must get enable all the time / every company ?? Why don't the ISP just make it available for everyone thus this kind of error will not occur ?? Or is there any benefit if the Reverse DNS get disable ??
