[Dovecot] vacation problem with sieve and sogo

[Pablo Luchetti]

Hi, I have a problem with dovecot's sieve and SOGo ( http://www.sogo.nu/ )

I have installed last version of sogo ( 1.3.6) in one virtual machine 
with ubuntu, lucid.
In another virtualmachine with ubuntu jaunty is running dovecot ( 
1:1.1.11-0ubuntu4.1 )

When try to activate vacation function, after the "PUTSCRIPT "sogo" 
command, the manage-sieve answer:

NO "Script name 'sogo' is reserved for internal use."

And fails.

But I found, telneting the mail server on port 2000 that if I change 
script name, all works fine:

SETACTIVE ""
OK "No scripts currently active."
PUTSCRIPT "prueba" {536+}
require ["vacation"];
if allof ( not exists ["list-help", "list-unsubscribe", 
"list-subscribe", "list-owner", "list-post", "list-archive", "list-id", 
"Mailing-List"], not header :comparator "i;ascii-casemap" :is 
"Precedence" ["list", "bulk", "junk"], not header :comparator 
"i;ascii-casemap" :matches "To" "Multiple recipients of*" ) {vacation 
:days 1 :addresses ["pluchetti at example.org", 
"pablo.luchetti at example.org"] text:
hoy es 27 de abril de 2011, y estoy probando el nuevo sogo. 10:40
.
;
}
redirect "pllis at educ.ar";
keep;

OK "Putscript completed."
SETACTIVE "prueba"
OK "Setactive completed."
logout
OK "Logout completed."
Connection closed by foreign host.

So, the question is:
Why does this happen?
How can I fix it ?
Any ideas?

Here are dovecot's version and config:
