Telnet to GWIA shows 220************** response

Inbound messages to GWIA fail

 

During troubleshooting of a problem with the GroupWise Internet Agent (GWIA), attempts to telnet from a workstation to GWIA (port 25) would generate a 220**************** response instead of the standard responses from GWIA (below)

 

GWIA should respond to an incoming connection with one of the following messages:

"220 domain.com GroupWise Internet Agent <version number>  Copyright (c) 1993-2008 Novell, Inc.  All rights reserved. Ready"

or

"220 domain.com Ready" (if the "Do not publish GroupWise information" box is checked in ConsoleOne)

 

The incoming telnet connection did show on the GWIA screen, but any subsequent commands (ehlo, mail from:, rcpt to:) would generate a "Syntax Error" message

Telnet sessions were connecting to the internal network through a Cisco VPN solution, which was somehow intercepting the telnet connection and responding with the 220 *************** message and interfering with the connection to GWIA.

 

Performing a telnet from inside of the network or from the server itself worked correctly and displayed the standard GWIA "Ready" response, and manually sending a message in to GWIA worked correctly.
