RE: Simple internal IP address resolution for mail

Not RFC compliant.  You should not be able to go to your own public IP
address

Ken,

Thanks - I'll look into that, but the local users aren't going through
any router - there are on one local subnet with a simple switch, the
only router is on the line out to the ISP - and is owned by the ISP.
But I think what you're saying is they may be able to get the ISP to
program the router so it redirects traffic bound for the external IP
address back to the internal LAN addresses.  There are no networking
people on site.

Hi Neil -

- when in the office (as there is no internal DNS server) this resolves

to the external IP address, and can not connect

If your networking people have half a brain, they should be able to fix
the problem at this point so that the router NATs the external IP
address to the internal IP address transparent to the client.
