"net" Attributes

plugin.net.internal-hosts
A PMX_TYPE_HASH object used by the "net" plugin to exempt internal hosts from network-based tests. Hosts in the IANA unroutables are always exempted:
10.0.0.0/8
127.0.0.0/8
172.16.0.0/12     
192.168.0.0/16

If hosts in other domains should be considered "internal", they should be added to this hash.

Type: PMX_TYPE_HASH

Default: none

plugin.net.trusted-relays
A PMX_TYPE_HASH object used by the "net" plug-in to skip over certain relays in the 'Received' header chain as it tries to find the first external relay. Certain network tests must only be run on the first external relay.

If this attribute is not provided, the "net" plug-in assumes that the first external IP address is the relay.

See also: PMX_EV_FUR under "Event Codes" in the Anti-Spam Engine Reference section, and core.event.fur under "Core Attributes" in the Anti-Spam Engine Attributes section.

Type: PMX_TYPE_HASH

Default: none

plugin.net.dns-servers
Specifies the default DNS servers. If no default DNS servers are specified in the plugin.net.dns-servers attribute, the net plug-in obtains the system DNS servers from the Windows registry. On UNIX systems, the DNS servers are referenced from /etc/resolv.conf if they're not provided with this attribute.

Type: PMX_TYPE_STRING

Default: takes the DNS server settings from the system default

plugin.net.dns-timeout
The maximum number of seconds to wait for a DNS reply.
Note
For backwards compatibility reasons, if plugin.net.dns-timeout is not set, the attribute plugin.re.dns-timeout is used.

Type: PMX_TYPE_INTEGER

Default: 2

plugin.net.dns-retry
The number of times to retry a failed DNS lookup.
Note
For backwards compatibility reasons, if plugin.net.dns-retry is not set, the attribute plugin.re.dns-retry is used.

Type: PMX_TYPE_INTEGER

Default: 2

plugin.net.skip-dns-checks
If set to 1, this disables all tests using DNS.
Note
It is not recommended to skip DNS checks

Type: PMX_TYPE_INTEGER

Default: 0
