XFOR: Mail Connector Dispatch Fails Against Postoffice on Unix (152903)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q152903 SYMPTOMS
When you use the Microsoft Exchange 4.0 MS Mail Connector against an MS
Mail Postoffice that is residing on a UNIX server, it will not dispatch
mail from the Postoffice. Messages will be successfully dispatched into the
Postoffice, but the following event ID will be generated by the Microsoft
Exchange PC MTA in the application event log upon attempting to retrieve
outbound mail from the Postoffice(s) on the UNIX computer:
Event ID: 4254
Unable to deliver mail to \\servername\maildata\P1\XXXXXXXX.0lk
MS Mail Connector (PC) MTA will retry in the next cycle.
CAUSE
Mail is not dispatched from the Postoffice because files on the UNIX system
are written in lower case. The Microsoft Exchange 4.0 Microsoft Mail
Connector requests creation of the file in upper case and expects
\P1\<prefix>.0LK files to be generated. Specifically, the semaphore file is
thought to be from another process when it is not in upper case. As a
result, mail will not be dispatched.
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
Service Pack. For information on obtaining the Service Pack, query on the
