Q216474: XFOR: Delivery Receipts, OV/VM (PROFS) Connector & the Internet

Article: Q216474
Product(s): Microsoft Exchange
Version(s): winnt:5.5
Operating System(s): 
Keyword(s): exc55 EXC55SP3Fix
Last Modified: 30-SEP-1999

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

When OfficeVision/VM (OV/VM) users send to the Internet by means of the OV/VM
(PROFS) and Internet Mail Service connector, they will receive delivery receipt
mail even though none was explicitly asked for.


RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For additional information, please see the following article in the
Microsoft Knowledge Base:

  Q191014 XGEN: How to Obtain the latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or
later:

Component: PROFS Connector

+---------------------------+
| File name    | Version    | 
+---------------------------+
| Exconmsg.dll | 5.5.2592.0 | 
+---------------------------+
| Lsvmhc.dll   | 5.5.2592.0 | 
+---------------------------+


STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.5. This problem was first corrected in Exchange Server 5.5 Service
Pack 3.

MORE INFORMATION
================

By default, all mail from the OV/VM environment is sent to Exchange Server with
the Delivery Receipt flag turned on. The OV/VM (PROFS) connector will pass this
to Exchange Server, and a delivery receipt is sent back. The OV/VM (PROFS)
connector converts the delivery receipt to a format recognized by the host as a
delivery receipt before delivering it to OV/VM. The mail manager in OV/VM will
then determine if the original user actually requested a delivery receipt (by an
.AK command). If the user did not ask for the receipt, the mail manager will
delete the message.

Taking advantage of Exchange Server's Internet Mail Service, host users are now
able to send and receive SMTP mail by means of the Internet Mail Service and
OV/VM Connector. However, a drawback to this feature is the handling of delivery
receipts. Because all messages originating from the host include the delivery
receipt tag, external SMTP mail servers that recognize this tag send a delivery
receipt back. However, by the time this receipt has traversed all the way back
to the OV/VM connector, it will be treated as a regular piece of mail. This
results in OV/VM users receiving a delivery receipt when sending to Internet
recipients.

Now we can change the behavior by adding the following INI parameter in the
Exchconn.ini file under [LME-PROFS] section:

  AlwaysReturnACK = Yes

If the INI parameter is set to No or not present, the PROFS connector will behave
as it does now. If the INI parameter is set to Yes, then the following will be
true:

- The connector ALWAYS responds with a ZIP A packet to host.

- The connector will turn off any delivery receipt requests in the header of
  the message if the sender does not request one.

- The connector will transmit the delivery receipt request if the sender does
  request one.
