I use a sieve filter to move spam email to user's Junk folder:
# cat spam_to_junk.sieve
require "fileinto";
if exists "X-Spam-Status" {
if header :contains "X-Spam-Status" "YES" {
fileinto "Junk";
stop;
} else {
}
}
if header :contains "subject" ["SPAM?"] {
fileinto "Junk";
stop;
}
Most time this filter works fine but occasionally it move non-spam in to
Junk folder. Here is an example, this email is from dovecot mailling
list and it end up in my Junk folder. Mailllog and header here. Would
someone help me to figure out what went wrong here?
Thanks.
Gao
