wodSmtp.dll and DrWtsn32 (General questions)

Hi,

We have an eMail server used in our application for sending bulk messages to students from the district.

We are having a problem where the application aborts every couple of days. I have captured the Dr. Watson output and was wondering if you have any ideas what we might check.

The application is sending hundreds of emails a day and works well most of the time.

The wodSmtp.dll version is 1.3.6.65

Dr. Watson
