PC MMTA: Err Msg: Mail Bag Is Locked by: F:P1\<hex>.0LK

• Microsoft Mail Multitasking MTA, version 3.2

SYMPTOMS

When the OS/2 Multitasking MTA (MMTA) is used with BW-Connect NFS for Windows NT, it does not deliver mail between postoffices that reside on a UNIX machine. If the MMTA parameters "Q123" are used, the following error will occur in the SESSION.LOG:

   Mail bag is locked by: F:P1\<hex>.0LK

CAUSE

Mail is not delivered because files on a UNIX system are written in lower case. The Microsoft Mail OS/2 MMTA expects \P1\<prefix>.0LK files to be in upper case. Specifically, the semaphore file is thought to be from another instance of External when it differs from the upper case .0LK files. As a result, mail is not dispatched.

RESOLUTION

To correct this problem, from Program Manager Main group, run the Control Panel. Select Network, Beame & Whiteside NFS Client, and Configure. From the Default Links category, choose either Upper Case or Preserve Case.

STATUS

Microsoft has confirmed this to be a problem in version 3.2 of Microsoft Mail Multitasking MTA. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
