How did you include your content-filter? Pre- or Post-Queue? Please show your
Configuration. "postconf -n" and master.cf.

The DISCARD cannot happen at the same time. How should this work? The first
time when Postfix can Discard a Mail is, when Postfix has taken it complete
from the Client, not before. If Postfix aborts the Connection before, the
Client will try to send the Mail again and again...

<Connect>
HELO xxx
MAIL FROM: yyy
RCP TO: zzz
DATA
<DATA>
.
<OK from Postfix>
<Here is the first moment where Postfix can Discard a Mail>

The REJECT can happen somewhere between <Connect> and OK.
