Spamassassin on my mail server uses a local dedicated caching DNS
server, and it is only service which uses it (it's specified in
local.cf).
The last 3 days I have logged about 500 failed DNS query errors to
senderscore.com, e.g.:
19-Apr-2021 13:28:01.367 query-errors: info: client @0x7f31c334a9a0
127.0.0.1#53689 (214.48.240.54.bl.score.senderscore.com): query failed
(SERVFAIL) for 214.48.240.54.bl.score.senderscore.com/IN/A at
../../../bin/named/query.c:9385
...where in the month prior there were about 10 failures logged in
total. It's failing on what looks like every inbound email.
From what I can see it's a genuine blocklist lookup by SA...
(RCVD_IN_RP_RNBL in 20_dnsbl_tests.cf) but the error rate is strange.
Am I the only one with high volume of lookup errors from that bl? :-)
or do I need to be looking for an issue locally...
