Hi,

I'm testing postscreen on our secondary smtp server.
First results:
https://rz-static.uni-hohenheim.de/hmayer/tmp/Screenshot-68.png
There are hardly anymore rejects. I did not yet adjust mailgraph for the
drops.

Statistics:
   UNIQ/TOTAL EVENT
    536/586 PASS NEW
     97/119 HANGUP
    808/974 PREGREET

But I'd prefer not to use DNSBL's by postcreen. It is for the logging.
Users occasionally ask for details if mail did not arrive.

If I try, I get:
Jul 6 10:17:00 smtp2 postfix/postscreen[23670]: PREGREET 34 after 0.52
from 90.148.159.227: HELO 90-148-159-227.saudi.net.sa??
Jul 6 10:17:00 smtp2 postfix/postscreen[23670]: panic:
postscreen_dnsbl_done: no blocklist cache entry for 90.148.159.227

in main.cf
postscreen_dnsbl_sites =
postscreen_greet_action = drop

in master.cf
smtp inet n - n - 1 postscreen
smtpd pass - - n - - smtpd
dnsblog unix - - n - 0 dnsblog

I also tried to comment dnsblog - same problem:
# dnsblog unix - - n - 0 dnsblog

Jul 6 10:25:14 smtp2 postfix/postscreen[24577]: PREGREET 47 after 0.49
from 123.219.54.120: HELO p5120-ipbfp402kobeminato.hyogo.ocn.ne.jp??
Jul 6 10:25:14 smtp2 postfix/postscreen[24577]: panic:

Jul 6 10:25:15 smtp2 postfix/master[24571]: warning: process
/usr/libexec/postfix/postscreen pid 24577 killed by signal 6

What am I doing wrong ?

Regards
Helga Mayer
