Re: Simple internal IP address resolution for mail

I would assume the salesman uses a modem to connection when outside the
office. Any possibility of having this person use a modem in the office
and connect to his ISP and get an external address?

Chris,

No active directory.  No internal DNS server.  No network people.  Just
a small account with an iSeries running POP/SMTP for email (along with
their distribution application). 

So you're saying there's no quick and dirty solution, other than
configuring an internal DNS server just to server one address - the
"mail.theircompany.com" one ?

The standard is to have an internal DNS server with all of your
private
IP address.  If they are running Active Directory, this is already in
place.  Change your DHCP scope to use the internal DNS server.  Make
sure your network people add the appropriate MX record on your
internal
DNS server to point to the internal name / IP address of your mail
server.

Subject: Simple internal IP address resolution for mail

I'm looking for an easy way to do the following.

- salesman with laptop accesses mail externally with Outlook Express
using the company's external IP address, by using POP server defined
as
mail.theircompany.com - works fine outside the office

- when in the office (as there is no internal DNS server) this
resolves
to the external IP address, and can not connect

- all I want to do is have mail.theircompany.com resolve on the local
LAN in the office to the internal IP address of the iSeries
(192.168.99.99) instead of the external public IP address (that their
ISP's DNS servers are returning)

Is there a simple way to do this using the 70-POP Server option in the
DHCP server configuration (which IS running on their iSeries), OR do I
have to configure a DNS server on the iSeries to resolve this ONE
address (mail.theircompany.com) and have the present DNS server (which
is actually the ISP's DSL router) continue to resolve all other
address
requests ?
