XFOR: Data Truncated in SMTP Protocol Log (159290)



The information in this article applies to:

  • Microsoft Exchange Server 4.0

This article was previously published under Q159290

SYMPTOMS

When you look at the SMTP protocol log for the Microsoft Exchange Internet Mail Connector (IMC), you may see that the data portion of a conversation is truncated.

CAUSE

The function calls being used to output the data to the log file have a buffer limited to 1024 bytes and first lines were not terminated with a new line parameter. For example, the function calls \*wvpsprintf() and wsprintf() have a buffer of only 1024 bytes.

RESOLUTION

Apply the fix referenced below. Function calls supporting larger buffer sizes are now used to output the data to the protocol log and first lines are now terminated with new lines. The function calls \* vsprintf() and sprint() are now used.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
