In the procmailrc man page it states:
w Wait for the filter or program to finish and check its exitcode
(normally ignored); if the filter is unsuccessful, then the text
will not have been filtered.
I'm being a bit dense today. Is this interpretation correct?
"Filter is unsuccessful" means the exit status of the filter was
non-zero and so procmail treats the message as having not been
delivered.
For example, I have this recipe:
:0 W: cksum.lock
| pycksum -v $HOME/tmp/spam.cache
If pycksum exits with a 0 status procmail will consider the message
delivered, right?
Thanks,
