DOCUMENT:Q193782 22-DEC-1999 [exchange] TITLE :XADM: Internet Mail Service Stops with Event IDs 4182, 12800 PRODUCT :Microsoft Exchange PROD/VER:winnt:5.5,5.5 SP1 OPER/SYS: KEYWORDS:exc55sp2fix exc55 exc55sp1 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, versions 5.5, 5.5 SP1 ------------------------------------------------------------------------------- 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: 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: 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.
