[Dovecot] dovecot + sieve

[maximatt]

Hi,

In ower mail system we use postfix and dovecot v1.2.10 with sieve plugin and
i think is work fine but.....

i need to have access to variables values like in these test script

     require ["enotify", "variables", "envelope"];
     keep;
     notify :importance "1" :message "TEST SIEVE ${from}: ${subject}"
"mailto:i_not_exist at hotmail.com";

but when i receive message, the values for "${from}" and "${subject}" are
empty.

i don't know the reasons about these (i'm some lost with these issue)..

if help ... i put in master.cf (postfix) these value for dovecot delivery:

   dovecot   unix  -       n       n       -       -       pipe
                    flags=DRhu user=mail:mail
argv=/etc/dovecot/libexec/deliver -f ${sender} -d ${recipient}

¿is here the problem or what could be?

thanks in advance!
