Access Violation When Inetinfo Receives Mail That Contains a Header of More Than 64 KB

This article has been archived. It is offered "as is" and will no longer be updated.
When the Simple Mail Transfer Protocol Service (SMTPSvc) component receives a mail message that contains a header of more than 64 kilobytes (KB), this may generate an access violation.
If the size of a mail header is more than about 64 KB, SMTPSvc shuts down incorrectly because it does not synchronize threads. Because SMTPSvc works as a part of Internet Information Services (IIS), the access violation occurs in the Inetinfo.exe file.
