NOTES.

TITLE
Permission Denied Error (800a0046) may occur using CDONTS mail option.

EXPLANATION
In attempting to use CDONTS, option 2, you may encounter this error when attempting to actually send a message.  This issue is described in detail in Microsoft Article ID # 197619.  The solution as Microsoft's article describes in the context of Battle Blog is to check your SMTP server permissions, assuming you have direct control over your server.  If not, I recommend you use either the more contemporary CDO based message system (option 1), or, if your host provides it, ASPMail (option 3).  CDONTS is considered a legacy protocol and therefore may not be supported or adequately maintained by hosting companies (they have to go out of there way to make sure it runs properly on a 2003 server).
