I have maildrop setup with a simple config to check mail using

is spam or something from maildrop?
Don't do this.
At the time maildrop is handling the mail it has already been
received by your mail system (MTA). There is no connection to the
original sender. Maildrop could only use the From: Sender: and
Received headers as bounce addresses and they are usually forged. In
the worst case you would be harassing somebody as innocent as you
yourself!
You have two choices:
1) Integrate the spamcheck to your MTA. Then the MTA could refuse the
mail at the time of reception. I know Postfix can do this, probably
most others as well.
2) Let maildrop tag, archive or delete the mail. Do not try to send it back.
Mail that is falsely reported as spam needs to be bounced back to the
sender so they know to resend. Just accepting it and deleting it isn't
acceptable. I wanted to use spamassassin-milter, but its not very
stable, so I am stuck calling spamassassin through maildrop. I don't
know what other options I really have to avoid sending bounces to forged
from: addresses.
