From the documentation: dns_available { yes | test[: name1 name2...] | no } (default: test) By default, SpamAssassin will query some default hosts on the internet to attempt to check if DNS is working or not. The problem is that it can introduce some delay if your network connection is down, and in some cases it can wrongly guess that DNS is unavailable because the test connections failed. SpamAssassin includes a default set of 13 servers, among which 3 are picked randomly. You can however specify your own list by specifying dns_available test: domain1.tld domain2.tld domain3.tldPlease note, the DNS test queries for NS records. SpamAssassin's network rules are run in parallel. This can cause overhead in terms of the number of file descriptors required; it is recommended that the minimum limit on file descriptors be raised to at least 256 for safety.
