Since upgrading to 2.3.0 / 0.5.0.1, incoming PDFs are getting mangled. It seems to be happening when I use vnd.dovecot.filter. When I comment out the block, things come through fine.

My filter block looks like this: require "vnd.dovecot.filter"; filter "bogofilter_filter";

    if header :contains "X-Bogosity" [
            "Spam, tests=bogofilter, spamicity=1.00",
            "Spam, tests=bogofilter, spamicity=0.99"
    ] {
        fileinto "spam/totally";
        stop;
    }
    elsif header :contains "X-Bogosity" "Spam," {
        fileinto "spam/probably";
        stop;
    }
    elsif header :contains "X-Bogosity" "Unsure," {
        fileinto "spam/maybe";
        stop;
    }

filter/bogofilter_filter looks like this: #!/bin/sh cat /dev/stdin | /usr/local/bin/bogofilter -p -e -c /path/to/bogofilter.cf

Images seem to come through fine. I didn't have this problem before the upgrade. It could easily be a problem with bogofilter, but I figured that I'd check here first to see if anybody else has an attachment-mangling issue with vnd.dovecot.filter.

exec /usr/local/bin/bogofilter -p -e -c /path/to/bogofilter.cf

Thank you! While that didn't fix the problem, it did clue me into trying
just "cat /dev/stdin" to conclude that it's bogofilter that's misbehaving.
