SYMPTOMS

When you send mail to a large distribution list (containing some invalid addresses) from a Pegasus Mail client to the Microsoft Exchange Server Internet Mail Service (IMS), the IMS may close. The IMS will log the following events:

   9001:
   An exception has occurred. Code: 0xc0000005 Flags: 0x00000000
   Address: 0x77f7d2ef

   Mail Service.  This may have resulted in a message not being delivered.
   Code: 0xc0000005 Flags: 0x00000000 Address: 0x77f7d2ef

The Dr. Watson dialog box displays the following information as well:

   An Application error has occurred and an application error log is being
   generated.
