how to login to Sieveshell?

[Su Li]

Hi,

I am trying to set up Sieve on Cyrus IMAP. I didn't use --disable-sieve when
I don ./configure.

I tested timsieved by "telnet localhost sieve" and got the answer back same
as install-sieve.html shows.

When I try "sievsshell localhost", sieveshell will ask me for password. I
not sure what password does it need, and how do I set one.

I also tried "sieveshell -u cyrus localhost". I used the same password for
IMAP login. It didn't work. 

I wonder, how do I set up a user for Sieve? Is there a admin user who can
set all filtering scripts?

Thanks,

Su
