Does it always fail, if you try to do a discard, just sometimes? I am using Dovecot 1.2.9
"dovecot-1.2-sieve-0.1.14" and discarding email seems to work fine.

The things I can think of are:

	1) Wrong privileges for deleting. What user does procmail / deliver run as?
	2) Old Bug in Sieve (http://www.dovecot.org/list/dovecot/2007-July/024290.html)
	3) If it fails just sometimes, what is the difference between discarded and nondiscarded mails.

If this does not turn up something, I do not have an idea what is going wrong. Only bugfix I
then can you provide with, is not to discard but to move those files to a folder 'SPAM' and delete
them by hand.
