Please Help!!!- We currently have a 64K Diginet Line and adsl. With our diginet line we get 8 static ip addresses. We currently have an Exchange 2003 server running as default collecting and sending our mail. Due to the increase in size of mail we want to send mail out on the adsl and recieve on the diginet line which our mx records point to.

Anyone got any ideas??? Please!!!!
 
Run a small linux box as a mailserver on your local LAN.
Set the linux box gateway to the IP of your ADSL router.
Set the smtp of the Exchange server to the IP of the linux box.
Done!
 
thanks but I dont want any linux on my network, we just scrapped all our linux machines. Any more suggestions?

Thanks in advance
 
use mercur, its a windows mail server, u can set it to do anything u want!
 
You can use Telkoms or your ADSL isp to relay mail through if you have one of their IP's assigned via DHCP? Just set exchange to forward all mail to that specific host and it should go out over your ADSL line being the least cost routing. What routing device are you using for the diginet and ADSL? You should also be able to set your router using policy based routing to send outbound SMTP traffic over ADSL.

Alternatively you can set the gateway on your exchange server to use the ADSL router to leave your network.

Just bear in mind that quite a lot of ADSL ip's are blacklisted with Spamcop/DNS Blacklists etc so your email might get stopped on the gateways of target mail systems.

OK, if you insist on giving M$ more bux...

Run a small windows box as a mailserver on your local LAN.
Use a mail collator/forwarder like Internet Anywhere - see review at http://downloads.theregister.co.uk/Windows/WebDev/InternetTools/ia-mailserver.html
There are many others available to choose from.
Set the windows box gateway to the IP of your ADSL router.
Set the smtp of the Exchange server to the IP of the windows box.
For all references to windows above, you can use either XP or 2000/2003 - don't recommend earlier versions.
Done!

Surely you could just set the gateway of your Exchange server to the ADSL gateway IP and that would take care of that?

Set the network settings to use the IP of the ADSL line. Normal windows network settings gateway. It would tell the server that the only way to send data out of the network is over that gateway.

Should work a treat.

Yes, your gateway setting doesn't handle traffic inbound it affects traffic outbound. Inbound is handled by the MX record and the router.

That was what I was thinking. Maybe a mail spooling account with one of the ISP's would be a good idea. Basically your mail server can then fetch and retrieve from the ISP's server. All mail would also go to the "mail spooling account" at the ISP and you could basically get rid off the 64K Diginet.

Aahh, OK. I'm no expert on email server configs, particularly M$ Exchange. If that'll do the trick, great stuff! If not, one caveat if you go the additional node route - most of those mail collator/forwarders also have their own settings to configure in-bound mail, so make sure there's no conflict with Exchange...

Just setup Routing and Remote Access and you can use Exchange to fetch email periodically. It will also sen out through that connection.

The only problem with that Gateway setting is when you have branch offices on different subnets. It will start looking for clients on the Internet?

If exchange is installed in the same Org then AD sites and services will take care of all of that on your private IP range (10.x.x.x) providing you have a VPN connecting it all together. Well you would need a vpn if it's all one site.

hi guys

When i set my network cards to the ip of my adsl it sends out like a treat but like mbs said then i dont recieve mail. Thanks for all the posts. The company doesnt want to pop off an isp like telkom because they deal with mass mails all day and need stuff to go out urgently.

Hmmm, interesting. Let me have a think about this.
 
surely there is some form of communication between the server before actually data gets transferred. With the wrong gateway address the reply to the initial connection request will go out the wrong connection?
