sieve-filter failure problems

[Jost Krieger]

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?

Yours
