Hi,
a very basic notification could be done by using an Outgoing Content Filter which has a condition of "Envelope Sender - Matches term in dictionary - " and Action: "Notify - Sender - Notify template:"
drawbacks:
- this simple content filter does not check if the user received this notification already - he will get the message every time he sends an email.
- the filter does not check if the connection was already authenticated smtp - perhaps use differnt listeners and check for correct listener in Conditions
regards,
Timo
