There are external factors that can cause the operating system to generate email messages without property information. Addressing these external factors can reduce or eliminate this situation.
The SMSMSE event sink component used for SMTP scanning, receives a NULL value for "IMailMsgProperties" argument (number 3 in the following declaration).
IMailMsgProperties *pMsg is a reference to the MailMsg object housing the current message content and properties. SMSMSE crashes when it tries to call SMTP using pMsg (which could be NULL in this case).
