Bug #: 6728
Summary: DNSBLs need a way to turn off queries based on BLOCKED
rules triggering
Product: Spamassassin
Version: SVN Trunk (Latest Devel Version)
Platform: PC
OS/Version: Windows 7
Status: NEW
Severity: normal
Priority: P2
Component: spamc/spamd
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
Need a way to make spamd recognize that a BLOCKED rule such as URIBL_BLOCKED is
triggered and hold off on subsequent DNSBL queries for 1 hour.
The 1 hour part should be configurable.
Subsequent delays will need a multiplier that is configurable and will be set
at 1.1 for initial tests.
This means:
Query returns answer indicating IP is blocked for DNS queries.
BLOCKED rule is triggered
SpamD recognizes the block and turns off queries for 1 hour for that RBL
1 hour elapses
Query returns answer indicating IP is blocked for DNS queries.
BLOCKED rule is triggered
SpamD recognizes the block and turns off queries for 1.1 hours for that RBL
...
We likely need something to define in a rules config such as:
block_disable List of Rules separated by commas,semicolons or whitespace
block_disable URIBL_BLACK,URIBL_GREY,URIBL_RED
Then if spamd picks up a BLOCKED rule and block_disable is defined, it can
disable those rules.
However, if we need an easier hack, we can modify the description of the rule
for BLOCKED to including something that is parse-able. such as adding
Temporarily Blocking Queries: URIBL_BLACK,URIBL_GREY,URIBL_RED to the
description.
This idea was split from bug 6724.
