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)
My system is an Ubuntu 18.04
Thanks,
Torsten
