Outlook 2002 issue

i am using a database that sends mass emails via a MAPI client, in this case Outlook XP. But because of the security features built into this version of outlook everytime the database tries to send message outlook asks if i want to allow this. If i select yes the message goes, but it asks this for every message and i'm tring to send about 1300 at a time.

Is there a way to turn this 'feature' off, or to automatically select yes to this question.
