I'm getting a behaviour with pigeonhole that I wasn't expecting. Am I
misunderstanding the design?
I run my messages through a vnd.dovecot.filter. It's essentially this:
filter "spam_filter";
if spamheaders {
fileinto "spam";
stop;
}
Mail stored in the spam folder is the filtered version, but the
implicit-keep message is the original, unfiltered message. If I add an
explicit keep; to the end, it stores the filtered version into my
inbox.
Based on the filter RFC, I was expecting the implicit keep to retain
the filtered version. Am I misinterpreting the spec?
I did a quick test, and I am not seeing any problems.
However, what is that spamheaders test in your script?
Hi Stephan,
The block looks like this:
        ### BOGOFILTER
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;
}
Bogofilter adds an X-Bogosity header. With the block as it is, when it
hits the implicit keep the message has no X-Bogosity header. When I
add 'keep;' to the end, it does have the header.
If it's just me, that's fine, as it's incredibly easy to work around.
What version is this? Please provide full config from dovecot -n.
Regards,
Stephan.
