Summary: Last External DNS Check for RBL module bug?
Product: Spamassassin
Version: 3.3.1
Platform: Other
OS/Version: Linux
Status: NEW
Severity: critical
Priority: P2
Component: spamassassin
AssignedTo: [email protected]

This is my first post. I tried to look at existing bug but did not find it.
I believe there is an issue with SpamAssassin 3.4.1 when it checks DNS for
RBLs.
I will enclose a sample email and the debug code. I hope you will find sometime
to check it out.
SA seems to go thru last external list of IP but failed on bad header. I may be
having bad configuration but this started to show up after I upgraded from SA
3.2.4 to 3.3.1. This problem renders my RBL checks for lastexternal hosts
useless and makes SA 3.3.1 not effective. This was not an issue with SA 3.2.4.
In the log, you will notice that SA only check 'unknown' which is internal host
and not last external. Here is the sample:
