Hello,

a query of SORBS results in REFUSED results.

Here is an example entry:

RCODE resolving 'rbldns10.sorbs.net/A/IN': 108.59.172.201#53

While some queries succeed and SpamAssassin appears to be able to use
SORBS, there are always *multiple* REFUSED results only for sorbs.net.

Am I exceeding the number of free queries that SORBS allows ?  If so, 
do

I need to register with SORBS (similar to how SpamHaus requires
registration to use their DQS service) ?  If so, how do I update my SA
configuration ?

Thanks,

SORBS has been ultra sensitive like that for a few years now, it allows 
lookups, then it doesn't, seconds later it does, I suspect an ill 
configured DoS protection mechanism that's overly paranoid, but good 
luck getting anyone their to listen.

uridnsbl_skip_domain question

2024-05-17 Thread Matus UHLAR - fantomas

Hi guys,

I have configured exclusion for some common domains e.g. gov.sk in SA:

uridnsbl_skip_domain [...] gov.sk slovensko.sk

However it seems that that domain is still queried:

 9826  68.951573127.0.0.1 → 127.0.0.1DNS 104 Standard query 0xbffe A 
mail.gov.sk.multi.uribl.com OPT

in SA 4 docs I see that:

   uridnsbl_skip_domain domain1 domain2 ...
   Specify a domain, or a number of domains, which should be skipped
   for the URIBL checks.  This is very useful to specify very common
   domains which are not going to be listed in URIBLs.

   In addition to trimmed domain, the full hostname is also checked
   from the list.

Do I have to exclude subdomains for each host too?
(this would kind of defeat the directive imho).

This is SA 3.4.6 (debian 11) which does not have the latter paragraph but I 
assume the difference is only in documentation
