I
don't beleive that exchange has a way of issuing an etrn command inside of it.
It also sounds like this issue is getting a little confused. Since you are
on a leased line ( I assume it is up 24x7) why use ETRN at
all?
My
understanding is that ETRN is used by the receiving mail server to say that
"Hey, I'm here, I'm online now, start spooling me my mail". The
sending mail server then immediately sends all mail for the receiving domain in
the queue. This is helpful if you are on dial-up, but with a leased
permanent connection should not be neccessary.
The
exchange server with a properly configed Internet connector should receive the
mail as it is processed through the imail relay when it comes in to the imail
server.

yeah, we "know" all that, ESMTP etc, stuff, but we can't figure out how to configure Exchange to do it.
And, even better, jumping around trying to do it, we broke Exchange's sending to us, which was working fine this morning.
You issue the ETRN, your server finds their server and sends the spool.
Who issues ETRN? We want their Exchange server, behind NAT, to come across the leased line to our ISP, to relay their mail through us.
Imail is set up correctly, and has msgs for their Exchange domain to be picked up by ETRN, but Exchange won't do it.
A couple of guys sent me add on pgms, but we'd really like to get Exchange to do it unassisted.
I'm looking for speicific steps in Exchange to make it pick its mail via ESMTP from our Imail relayer.
Thanks,
Len

You get nothing at the telnet prompt but a little note about stuff happening OK.

Ok, as a last resort, we can do that, but how is telnet is going to inject the msgs ETRN-received from mymailserver.com into theirmailserver.com domain in Exchange?
Certainly (Len, you, naive sucker!), Exchange can be configured to this?
The situation is perfectly analogous to mymailserver.com acting as a "bastion host" for theirmailserver.com. Certainly (there he goes again!), Exchange, somewhere in all its infernal complexity and opaque documenation, can handle this?
Len
=====================
Set up an AT or batch task to wake up every half an hour or so and run some
sort of macro that does:
start:
Telnet yourmailserver.com 25
ETRN @hisdomain.com
quit
exit
sleep 30 minutes
goto start
That is more of a conceptual than it is a working model. I use a small VB
executable using "send keys" for one client. Not so elegant, but has been
running without a hitch for near a year and a half now. Hope that helps,
-V
