Bug ID: 7881
Summary: sa-learn queries uribl for already known messages
Product: Spamassassin
Version: 3.4.4
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Learner
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: Undefined
When running sa-learn on already known messages uribl queries for urls in them
are made. This can result in getting blacklisted by uribl (URIBL_BLOCKED) due
to too many requests in a short time if one has a lot messages. A caching name
server doesn't help, as a lot of different urls can be contained in the
messages.
How to reproduce:
1. Start tcpdump to obtain all queries made:
tcpdump -i lo udp and port 53 | grep uribl
If you don't use a local dns server you might need to adjust "lo" to your
network device.
2. Run sa-learn, e.g.
/usr/bin/sa-learn --ham /home/USER/Maildir/cur/
3. You can see in the output of tcpdump a lot domains like
example.org.multi.uribl.com. .
4. Repeat running sa-learn.
5. You see the dns queries, again.
My bayes_seen file seems to get updated, at least the file's timestamp changes.
Running sa-learn with -L gets rid of the queries and tcpdump's output (also
related: bug 5837 ). The issue isn't general queries of sa-learn though, but
that they are done for already known messages.
