I've got a dedicated line client who has an Exchange server behind NAT and
ip address a.b.c.d. Exchange is programmed to come over the leased line a
pick up its mail from my Imail machine.
I have an MX record for hisdomain.com pointing at mail.mydomain.com. So
mail for hisdomain.com get to delivered to mail.domain.com for relaying on.
If I've understood ipswitch, it's in NT's hosts file that Imail looks first
to find the relaying destinations. So should I have a line in hosts:
a.b.c.d hisdomain.com
But a.b.c.d. is the ip address with name gw-hisdomain.mydomain.com, not
simply hisdomain.com (I host his web server under than name�).
In NT's hosts file, I should have the ip address of his router's NAT
outside interface associated with what?
Does it matter if I have hosts set to:
a.b.c.d hisdomain
when in my DNS, there is:
gw-hisdomain.mydomain.com. IN A a.b.c.d
????
Also, is there any param I can set to prevent Imail from attempting to
deliver his mail to the destination ip?? ie, any way to "passivate"
Imail's relaying so that it stores but doesn't attempt to forward, and
waits passively for him to pick it up? I'd rather not clog up his leased
line with Imail banging awaying impotently on his router's outside i/f.
Thanks,
Len
