XFOR: New Feature for Setting Size Limit for Internet Mail Service

ID: Q231303


The information in this article applies to:


SUMMARY

The Internet Mail Service allows for seting the same Inbound and Outbound size restrictions.

The current behavior is by design. Currently, the product allows for a size limit to be set for the Exchange Server Internet Mail Service that is used for both incoming and outgoing messages. A new feature was added to allow administrators to control the size of incoming and outgoing messages independantly.


MORE INFORMATION

This supported feature is now available from Microsoft, but has not been fully regression tested and should be applied only to systems having a specific need for it. If you are not severely affected by the lack of this feature, Microsoft recommends that you wait for the next Microsoft Exchange Server version 5.5 service pack 3 that contains this feature.

To obtain this feature immediately, contact Microsoft Product Support Services. For a complete list of Microsoft Product Support Services phone numbers and information on support costs, please go to the following address on the World Wide Web:

The combination of two new registry settings, and an update to the Exchange Server Internet Mail Server, will implement the new feature.

The registry setting used to remap the attribute is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIMC\Parameters
Value: OutboundSizeLimit REG_DWORD and Value: InboundSizeLimit REG_DWORD.

These values are set in (K) the same way the "Message Size" is set in the Administrator program.

Please note that the new feature should not be used in coordination with the previous limit settings found on the General tab of the Internet Mail Service Property page of the Administrator program. Before implementing this feature, set the Message Size radio button to No Limit. The registry settings should take precedence, but in some cases, the size limitation may not be applied as expected. If only one limit is being used for either Outbound or Inbound, it is recommended that you create both registry values with a value. A setting of 0 will indicate no limit. The maximum registry value allowed is 4,294,967,295.
