dovecot - Nov 2011 - Getting started with sieve and conversion from procmail

Hi,

I have a fedora15 system with dovecot-v2.0.15, dovecot-pigeonhole and
and amavisd-new and would like to implement it on my system using
postfix. I've read the basic wiki documentation, but I really can't
figure out the proper starting point in my case. I've enabled
"protocol lda" in 15-lda.conf and added "sieve" to the list
of
mail_plugins.

I'm trying to adapt postfix to use deliver as its LDA for multiple
virtual domains. I've added the following to master.cf:

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=dovecot:dovecot argv=/usr/libexec/dovecot/deliver -f
${sender} -d ${recipient} -a "${RECIPIENT}"

Is that the proper format? Is it okay to use the dovecot user here, or
should I create a new user? What permissions does this user need to
possess?

I've added the following to main.cf:

dovecot_destination_recipient_limit = 1
virtual_transport = dovecot

I have a number of procmail scripts and I've converted them to sieve,
but they didn't convert very well. Can someone show me how to convert
the following:

:0
{
    :0 fhW
    | /home/alex/bin/process-mail.pl
}

The script skipped right over that. I'm also trying to convert the
following:

:0
* (RCVD_IN_DNSWL_HI|RCVD_IN_DNSWL_LOW|RCVD_IN_HOSTKARMA_W)
* !USER_IN_WHITELIST
* !BAYES_00
* !URIBL_
* !KHOP_RCVD_UNTRUST
* !RCVD_IN_DNSWL_MED
* !SPF_SOFTFAIL
* SPF_HELO_PASS
* SPF_PASS
{
        LOG="DNSWL: "
        :0:
        whitelist/dnswl
}

The script only produced the following:

if true {
if true {
if true {
if true {
if true {
if true {
if true {
if true {
if true {
if true {
        fileinto "{";
        fileinto "      LOG="DNSWL: "";
        fileinto "      :0:";
        fileinto "      whitelist/dnswl";
        fileinto "}";
}

Any ideas greatly appreciated.

Thanks,
Alex

The Sieve language doesn't support invoking external programs. You can 
execute this program before Sieve, for instance by wrapping the LDA 
invocation. Also, there is a non-standard (an still pretty much 
experimental) language extension for this, as provided by the pipe plugin:

I'm not sure what these rules are supposed to mean (most conditions are 
obscured in variables), but by the looks of things these should also be 
executed outside Sieve as well. If all those conditions map to simple 
header and envelope tests, you can provide a Sieve alternative. However, 
I think USER_IN_WHITELIST queries some external list and that too is not 
(currently) possible from Pigeonhole Sieve. Also, it is not possible to 
change the log prefix from Sieve (as suggested by LOG=).
