Help with evaluation needed.

Hi,


I've been evaluating the mail washer for a few minutes. What do these messages in the log file mean:

Code: Select all

2020-01-16 20:26:06 [713017088] Error: RBLFilter::Filter::RBLSocketException - (RBL zen.spamhaus.org) - 11.137.147.136.zen.spamhaus.org rbl -3 Temporary failure in name resolution
2020-01-16 20:26:06 [713017088] Error: DNSSocket::DoQuery - StdException - UDPSocket::CheckSocketStatus - error writing from the socket [] :: failed with code 13: Permission denied, dnsServers(2a01:4f8:0:a0a1::add:1010)
Is this a problem? If so, what have I configured incorrectly?

My system is an Ubuntu 18.04

Thanks,
Torsten

It looks like your dns is setup incorrectly as it can't resolve to that address.

Following up here with some additional info:

See this article:

https://www.spamhaus.org/faq/section/DNSBL%20Usage#366

in the "How do i check my DNS server results?" section. The "dig" commands in there should help to debug your dns setup.
