problem is with slow poll_dns_idle and tests_pri_500
i looked up that it means that the dns response is slow, i use local bind9 and the quary time when i look for sites is ~30-40ms
and most of my mails take 4-8 seconds to deliver, that is to much, some are delivered in 200-300ms and this is how it is supposed to be,

can you help me with this issu ?

The poll_dns_idle is just a state where SpamAssassin is waiting for
DNS replies to come in or a timeout to expire. Apparently at least
some (if not all) of your DNS queries are not being answered.
Typically these are RBS or URIDNSBL tests, so perhaps one of the
queried black/white-lists is down, or some perhaps there is a
DNS resolver problem at your site.

The 14+ (15) seconds timeout comes from your 'rbl_timeout' setting.
You may decrease this value, perhaps down to 6 seconds, if your
DNS resolving is otherwise reasonably fast.

Nevertheless, you should investigate which DNS query is stalled
by adding a '--debug=async' debug area to you spamd or spamassassin,
e.g.:

$ spamassassin -D timing,async -t <test.msg

i found that lines disturbing:

bel-pol.com.pl is my domain, i wonder why is it as a link with the rhsbl.ahbl.org

this line is the problem
maj  2 10:03:34.461 [16555] dbg: async: aborting after 8.252 s, deadline shrunk: DNSBL-A, dns:A:bel-pol.com.pl.rhsbl.ahbl.org.

any idea how to fix that ?

edit:
i just found that in /usr/share/spamassassin/

i just want to ask for other rbl that is not offline, i dont want to stay with no spam protection except my own rules,
as for now i had to disable the rhsbl.ahbl.org adress

SpamAssassin is trying to check SBL service with your domain name, this is normal.

If you want to disable rhsbl.ahbl.org, just set its score to 0 in /etc/mail/spamassassin/local.cf. For example:

1: Check which rule defines 'rhsbl.ahbl.org':

# cd /usr/share/spamassassin/
# grep -i 'ahbl' 20_dnsbl_tests.cf 
header DNS_FROM_AHBL_RHSBL      eval:check_rbl_envfrom('ahbl', 'rhsbl.ahbl.org.')
describe DNS_FROM_AHBL_RHSBL    Envelope sender listed in dnsbl.ahbl.org
tflags DNS_FROM_AHBL_RHSBL      net
reuse  DNS_FROM_AHBL_RHSBL

2: You see the rule name is DNS_FROM_AHBL_RHSBL. So turn it off in /etc/mail/spamassassin/local.cf:

score DNS_FROM_AHBL_RHSBL 0
