I am far from an expert, but Clamav is a good starting point. Check out how to set it up.
I'm only getting locally generated spam, and it's marked with ***SPAM*** in the subject.
I haven't yet worried about it because it's a small problem for me at the moment.
TBH, spam is a larger subject than just one or two commands, and I still have a lot of reading (and asking of questions  )to go myself.
Cheers,
Nap
