Re: [IMail Forum] ERTN by Exchange over leased line?

[Vaughn Thurman]

No sweat man!  this is a feature of ESMTP.  You issue the ETRN, your server finds their server and sends the spool.  You get nothing at the telnet prompt but a little note about stuff happening OK. -V   ----- Original Message ----- From: Len Conrad To: [EMAIL PROTECTED] Sent: Monday, August 23, 1999 11:29 AM Subject: Re: [IMail Forum] ERTN by Exchange over leased line? 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 ----- Original Message ----- From: Len Conrad <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, August 23, 1999 10:19 AM Subject: [IMail Forum] ERTN by Exchange over leased line? > Our client connects to us via a leased line.  He has Exchange behind NAT, > so Imail forwarding can't reach it by MX connection. > > We'd like his Exhange to us ESTMP and ETRN to come pick up the mail.  We > can't see how to configure Exchange to this.
