We are testing 5.5 and are experiencing something strange. We have several domains on the machine and since the upgrade some domains show up as "spam detected" on the outgoing mail graph on the overview screen. We don't can outgoing mails for spam, so I did't expect to see this here.
Also on the "Outgoing Destinations" I see our domains as destinations for threat messages. (This seems quite alright)
Could someone confirm, that this is the new default behaviour? Unfortunately I don't have the documentation for 5.5 yet.
