Filtering posts and immediately / later completely removing

[loomic]

I`m filtering spam posts by rejecting them at header download. What does rejecting mean ? Will that posts completely ignored ? Will that post stored in database and just marked as filtered ?
And how to remove older post that are marked filtered completely from database ?

When you filter at the header download level, the things you filter out never make it into the database. They're downloaded, then deleted out of hand. It's a good way to keep the database sizes down.

Thats how it should work.

Thx loomic.
