Sieve stopped working

Hi,

I have installed RoundCube a couple of years ago on a Snow Leopard server. All nice and dandy up to today.

Sieve has stopped working and I have spent hours and been unable so far to get it up and running again.

When I run ps aux |grep sieve it is not returning anything to me suggesting that the problem is not with sieve it-self but rather with Dovecot not starting the sieve.

If anyone could give me some leads I can't think of anyting else.

netstat -a |grep 2000 returns

returns nothing

telnet localhost 2000

Trying ::1...

telnet: connect to address ::1: Connection refused

Trying fe80::1...

telnet: connect to address fe80::1: Connection refused

Trying 127.0.0.1...

telnet: connect to address 127.0.0.1: Connection refused

telnet: Unable to connect to remote host

The rest of mail functions not problem (IMAP, SMTP...).

Thanks in advance

Beno
