Server "Scripting error 100" with "Send Mail" sends out a lot of mails...
A server side script sometimes gives a Scripting Error (100) with the Send Mail command. This script runs every day without any problem and its goal is to send out emails to new clients.
But every 3 months or so it gives the above error and the script keeps running and the result is that hundreds of mails are automatically sent out to clients... but not to new clients, but to old clients as well (very annoying).
I don't understand what's causing the issue: the script runs fine daily, but 1 out of 100 times, it gives the error. I understood the 100 error is about a file missing, but the mails don't have attachments.
So what could be causing this? Any help is much appreciated!!
