[Dovecot] qmail-ldap LDA Delivery and sieve

[Ruda Porto Filgueiras]

Hi,

I'm using dovecot 2.1.7 on debian Squeeze with ldap integration.
Almost everything is working fine and I would link to thank all
developers for this amazing piece of software.

But after changing my qmail-ldap to do LDA integration get all the
benefits from LDA and sieve, some emails return with failure like
this:

<sar at mondialline.com.br>:
lda(sar): Fatal: Unknown argument: sar
Usage: dovecot-lda [-c <config file>] [-a <address>] [-d <username>] [-p <path>]
                   [-f <envelope sender>] [-m <mailbox>] [-e] [-k]

It happens on messanges that could not be delivered and need to be
returned to the sender.
I'm using the configuration described on wiki to do qmail-ldap
integration: http://wiki.dovecot.org/HowTo/qmailldap

The relevant delivery command is:
| /usr/lib/dovecot/dovecot-lda -a $RECIPIENT -f $SENDER -d $USER

I also tried to use this way, as documented here:
http://wiki2.dovecot.org/LDA/Qmail
| /var/qmail/bin/preline -f /usr/lib/dovecot/dovecot-lda

But in that case, some sieve plugins can't detect the mail recipient,
like vacation plugin.

Finally, the vacation plugin also is not doing email forwarding when I
use the first delivery option above.

Follow my settings:

# LDAP

user_attrs = uidNumber=11184,gidNumber=2110
user_filter = (&(objectClass=qmailUser)(uid=%u)(accountStatus=active))

pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountStatus=active))
iterate_attrs = uid=user
iterate_filter = (&(objectClass=qmailUser)(accountStatus=active))
