{AcceptedInternal} ?

[Niklaas Baudet von Gersdorff]

In the logs is see incoming mails having the note

  {AcceptedInternal}

What does it mean? It's not only for mails are sent internally
(between domains I host) but also for mails that arrive from
foreign servers. I'm wondering whether I configured amavisd-new
correctly.

I also noticed {AcceptedOutbound} which is obvious and is logged
for emails that are sent to domains I don't host. 

I searched for an explanation of the logs on the web but I didn't
find anything.
