SYMPTOMS
When the Internet Mail Service receives an inbound Internet message that contains a corrupted encapsulation address, it generates the following error messages in the event log and shuts down:
Event: 4182
Source: MSExchangeIMC
Type: Error
Category: Internal Processing
Description: A serious error has occurred while trying to send mail
into the Exchange Information Store. The Internet Mail Service is being
shut down.
Event: 12800
Source: MSExchangeIS
Type: Error
Category: Content Engine
Description: Message processing failed because there is not enough
available memory (8007000E-F20000FF).
CAUSE
The Internet Mail Service submits a message to the information store, which in turn parses the addresses to get the corresponding display names. It detects the corrupted address and generates MAPI_E_CALL_FAILED, but later this error is overwritten as MAPI_E_NOT_ENOUGH_MEMORY.
The information store logs an Event ID: 12800, and the error is returned to the Internet Mail Service. The Internet Mail Service detects this as a serious error and logs an Event ID: 4182, shutting itself down.
RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
191014 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: Information Store
File Name Version
-----------------------
Gapi32.dll 5.5.2417.0
Mdbmsg.dll 5.5.2417.0
Store.exe 5.5.2417.0
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 2.
MORE INFORMATION
When a message containing one-off addresses goes through several connectors, it is encapsulated to its native format. For example, when the SMTP address someone@microsoft.com goes through an X.400 Connector, it is encapsulated as:
IMCEAEX-_O=Organization_OU=Site_CN=ContainerName_CN=
someone@microsoft.com
NOTE: The above address is one string; it has been wrapped for readability.
Further, the container name is encapsulated as follows: Any non- alphanumeric characters (with the exception of "=", "-", and "/") are encoded as "+xx" (without quotation marks), where xx is hexadecimal digit of that character. So ":" is encapsulated as +3b, where 3b is the ASCII representation of ":".
The fix is to correct the code that overwrites the error.
