[Kroupware] Using Sieve

[Carlo Kok]

I've checked the faq and noticed that it's possible to use Sieve, but 
I'm unable to use sieveshell:
[root bin]# ./sieveshell localhost
connecting to localhost
unable to connect to server at ./sieveshell line 174.
[root bin]# ./sieveshell 10.1.1.101
connecting to 10.1.1.101
unable to connect to server at ./sieveshell line 174.


Telnetting to localhost:2000 works just fine, and I get a few replies:
"IMPLEMENTATION" "Cyrus timsieved v2.1.14"
"SASL" "PLAIN"
"SIEVE" "fileinto reject envelope vacation imapflags notify subaddress 
relational regex"
"STARTTLS"
OK

Anyone knows what I'm doing wrong?

Thanks,

Carlo Kok
