I've been using the dbconnector and seem to have everything working OK, except for triggering the "delivered to remote host" event (I am successfully using "ready to deliver", "local errors" and "remote errors").

I can see the delivery information in the appropriate email architect journals but am not getting anything to the database. I, currently, have no filters applied (once testing is done, I will apply filters to exclude the bulk of the emails sent).

First of all, please go to DBConnection Message Event: When an email is delivered to an remote host and please make sure:
Enable Connector is checked.

Secondly, send a test email, and go to Journal->Message Relay and make sure this email has been relayed.
Finally, go to Journal->System Error and see if there is any error about DBConnector.

By the way, could you also send me (our support email address) the SQL statement that you set in DBConnector?

That was it, I missed checking the enable connector. Thanks
