The Edge Transport server's transport process fails during an e-mail address rewrite on an Exchange Server 2007 server

View products that this article applies to.

Symptoms

On a Microsoft Exchange Server 2007 Edge Transport server, the transport process fails in certain e-mail address rewrite scenarios. This happens because an external e-mail is sent to a specific internal recipient e-mail address. When this occurs, the transport process fails at the "Rcpt To:" part of the SMTP conversation. When the transport process restarts, the remote server is likely to redeliver this external e-mail, which causes the transport process to fail again.

When this problem occurs, the following event is logged in the Application log:
Event Type: Error 
Event Source: MSExchange Common 
Event Category: General  
Event ID: 4999 
Description: 
Watson report about to be sent to dw20.exe for process id: <ID>, with parameters: E12, c-RTL-AMD64, <version number>, edgetransport,
M.E.M.EdgeAgents, M.E.M.A.StringBlock.ReadStringUnsafe, system.indexoutofrangeexception, be38, <version number>. ErrorReportingEnabled: False

Cause

During the e-mail address rewrite process, the appropriate address rewrite entry must be located. In certain scenarios, the entry lookup mechanism returns an invalid result. This causes the transport process to crash.
