The last line is what is causing your problem. Once you have a
delivery instruction, maildrop stops processing the filter files. If
there is no delivery instruction in maildroprc, then it will continue
on to $HOME/.mailfilter automatically. If there is no delivery
instruction there, it will deliver to your MAILDROPDEFAULT location.
So just leave off that last line. Your maildroprc should look like
this:
import USER
import HOME
xfilter "/usr/local/bin/filter.php $USER"
if ( /^SPAMSPAMSPAMSPAM/ )
{
to /dev/null
}
One other comment... Your check is a bit dangerous. While it is
unlikely that a valid email would have a line like that, you would be
better off adding a normal header line to look for. Something like
this:
X-MyScan-Results: SPAMSPAMSPAMSPAM
You could also leave the header in there all the time with a "NotSpam"
marker so that you could tell that the mail had been scanned.
