Hi to all,
Recently, I've installed the new Slackware 15 with, on board, postfix 3.6.
I come from an old Slackware 13.37 with a postfix 2.9 and I would like to update... but...

The main.cf and master.cf coming from old postfix seem to work but, in the main.cf there are, in "smtpd_recipient_restrictions" area, three checks:
check_policy_service unix:private/policy-spf,
check_policy_service unix:private/CheckDNSBL,
check_policy_service inet:127.0.0.1:10026,

the last row checks, on a Db present on other server, if the destination recipient exists. So, the last check doesn't work work and, randomly, I have also some error in CheckDNSBL script (written in Perl but usually working...)

I try to close this checks in "{}" with no results...
It seem like working only the first (or the first two checks) but not all the three together.

Someone has had the same problem or has a good advice for me to solve?

Thanks in advance for reading.
