Emails not going through, ExplicitlyDiscarded, HADISCARD

Hi,

We got an application sending out emails internally to our end users, it does so in bulks of about 50 or so. The application sends via a Exchange 2013 receive connector where the application server is listed as an allowed relay.

About 30% of the emails go through fine, but most are dropped in Exchange as such:

Timestamp SourceContext Source EventId

2/04/2015 13:02 ExplicitlyDiscarded SMTP HADISCARD

Its different recipients that get dropped every time and no other issues sending to any of these users.
