SYMPTOMS
When the External Mail program (EXTERNAL.EXE) encounters a mailbag contention problem, it tries to generate a report to go into the SYSTEM.LOG file. If the message has more than three recipients on a postoffice, the External Mail program may stop responding (hang or crash). In the OS/2 environment, the following SYS3175 message can result:

A program in this session encountered a problem and cannot continue.

If the report is generated, it may list recipients that actually did receive the message rather than list only the recipient whose mailbag could not be accessed.

Similar delivery problems, such as a corrupted or bad address, a bad group, or an empty or missing mailbag, may also generate the SYS3175 error.



CAUSE
These errors can occur when multiple recipients are specified for one postoffice and one of the recipients experiences a delivery problem. As the External Mail program tries to create the SYSTEM.LOG report, memory can be corrupted.

This problem does not occur for mail sent from user to user within one postoffice.



STATUS
Microsoft has confirmed this to be a problem in version 3.2.9 of the External Mail program. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
