[ILUG] Postfix problems with spamhaus blacklists

[Niall O Broin]

I use the spamhaus blacklist with various SMTP servers and it works nicely. 
However, recently on a server running Postfix 1.1.11 (yes, I know) it appears 
to have stopped working properly. I get lots of messages such as this in the 
logs:

Apr 17 00:41:31 pogo1 postfix/smtpd[26325]: warning:        \ 
230.192.141.69.sbl-xbl.spamhaus.org: RBL lookup error:      \
Name service error for 230.192.141.69.sbl-xbl.spamhaus.org: \
Host not found, try again


Now surely in the normal course of event, this is (hopefully) what you'll see 
more of i.e. failed lookups because the host is NOT in the list. So, why is 
that being reported? Also, in the current logs I am seeing NO RBL rejected 
messages. I suppose it's possible that the spammers have stopped sending mail 
to this server, but I doubt it, somehow.
