sieve script not applied

[Joan Aymà]

Hi everyone,

I installed all-new server postfix+amavis+dovecot and pigeonhole. 
Clients, thunderbird and roundcube creates sieve scripts ok and changed 
ones are seen by eatch other, so server at 4190 accepts the scripts and 
ensure they are created.
But filters onto new mail isn't applied. Example:
# rule:[guifinet]
if header :contains :comparator "i;octet" "subject" "[guifi-"
{
	fileinto "INBOX.guifinet";
}

Isn't the rule correct?

Didn't find any troubleshooting on this topic. Any ideas?

Thanks.
