I have and account on one of the cPanel servers and I love the Track Delivery feature.
I recently got another account on DirectAdmin and have been playing with the in’s and outs, but one feature I cannot seem to find is the Track Delivery function.
Is there an equivalent to the Delivery Report on Direct Admin?
In/Out by each email account is the closest you get, I believe. 
I’m more interested in seeing if something was filtered and by what rule, delivered, errored, the destination, etc.
Eximstats data is used by cPanel to generate it.

There is no equivalent on DirectAdmin, but you may find that you don’t need it as much. Email doesn’t get rejected by individual rules on the inbound unless you configure it to, you can adjust your configuration if you’d like to instead move email to a folder that meets a certain criteria and then review it there, etc. We only reject for major RBL listing on these servers.
