I can see that my sieve_before script successfully sends the message off to spamc/spamd - however the message ends up in my mailbox with only the pre-existing X-Spam headers (I had expected them to be replaced or to see duplicates). I thought I'd try to just strip them from incoming mail so I used deleteheader, I got a trace saying it matches and deletes the headers, then sends the mail off to spamc/spamd - but the message that ends up in my mailbox has the headers that were presumably deleted.
I cannot reproduce this with master. Keep and implicit keep act the same. My filter program successfully changes the message and the deleteheader commands properly drop the indicated headers.
What version is this? What is your configuration (output from
dovecot -n)
My before script sends to spamc or does deleteheader (as noted) but user script does:
# rule:[mailman lists with mailboxes] if allof( header :matches "List-Id" "*<*.*", mailboxexists "${2}" ) { fileinto "${2}"; stop; }
# rule:[discard duplicates] if duplicate { discard; }
keep;
I don't see header problems in mail that ends up ina fileinto'd mailbox, just my INBOX - I suspect it's interaction with the 'duplicate' implementation (which the RFC says operates on the original un-modified message).
