cyrus murder sieve and quota

[roos]

Helo. 

1.When we try to interact with sieve on frontend we get the following:

S: "IMPLEMENTATION" "Cyrus timsieved v2.2.12-Debian-2.2.12-4"
S: "SASL" "LOGIN PLAIN"
S: "SIEVE" "fileinto reject envelope vacation imapflags notify
subaddress relational comparator-i;ascii-numeric regex"
S: OK
C: AUTHENTICATE "LOGIN"
S: {12}
S: DXNlcasm5hbWU6
C: "cm9vcw=="
S: {12}
S: SGFdzc3ddvcmQ6
C: "YmFyYWJha2E="
S: OK
C: PUTSCRIPT "roos" {252+} require ["fileinto", "reject", "vacation"];
if header :matches "From" "*"{ vacation :days 1 "2"; } if header
:contains "From" "asd"{ discard; } if header :contains "To" "asd"{
discard; } if header :contains "To" "asdsd"{ discard; }
S: BYE (REFERRAL "sieve://n2.mail.internal") "Try Remote."

Does it mean that we have to connect directly to backend? I
didn't saw a sieve_proxy daemon in murder.

2. When we try to set quota for user's mailbox during interaction with
frontend we get:

 couldn't set quota for user/a-a : try NO [REFERRAL
 imap://;AUTH=*@n2.mail.internal/user/a-a] Remote mailbox

Does it mean the same? Murder wants us to connect directly to backand
for this task?

Please say how to overcome these. Thank you.
