I use sieve-filter for postprocessing misclassified mail. For false positives I use the following script:

require [ "variables", "include", "fileinto" ];

global [ "FORCENOSPAM", "ext", "ext1" ];

set "FORCENOSPAM" "YES";

fileinto "JUNK-PRENOUCE";

if header :matches "Delivered-To" "*+*@*" {
   set "ext" "${2}";
   set "ext1" "${2}";
}

include :personal "production";

FORCENOSPAM suppresses the spam handling and the Delivered-To stuff tries to regenerate envelope info.

This is my crontab entry: 1-57/4 * * * * cd ~kriegjcb; /usr/local/dovecot/bin/sieve-filter -v -e -W -u kriegjcb -m Spam/U0-failed ~kriegjcb/sieve/nospamfilter.sieve Spam/U0

Most things work fine, but a few of my rules will try to forward mail. This will fail and my idea was I handle this manually from the folder Spam/U0-failed.

Unfortunately the mail will arrive there but will also be left in the source folder Spam/U0 and will be processed again every 4 minutes ...

This is probably not intentional?
