DNS Lookup to Separate the domain part of a hostname
This DNS lookup helps you find the main domain part of a hostname. Sometimes it is called two level TLDs and three level TLDs.
# Separates the domain part of a hostname - ftp.perkel.com returns perkel.com
# DNS lookup returns 127.0.0.1 for single level domains
# DNS lookup returns 127.0.0.2 for two level domains
# DNS lookup returns 127.0.0.3 for three level domains
warn !condition = ${if eq{$sender_host_name}{}}
dnslists = rb.junkemailfilter.com/$sender_host_name
set acl_c_rb = $dnslist_value
warn condition = ${if eq{$acl_c_rb}{127.0.0.1}}
set acl_c_sender_host_domain = ${sg{$sender_host_name}{\N^.*\.(.*\..*)$\N}{\$1}}
add_header = X-Sender-Domain: $acl_c_sender_host_domain
warn condition = ${if eq{$acl_c_rb}{127.0.0.2}}
set acl_c_sender_host_domain = ${sg{$sender_host_name}{\N^.*\.(.*\..*\..*)$\N}{\$1}}
add_header = X-Sender-Domain: $acl_c_sender_host_domain
warn condition = ${if eq{$acl_c_rb}{127.0.0.3}}
set acl_c_sender_host_domain = ${sg{$sender_host_name}{\N^.*\.(.*\..*\..*\..*)$\N}{\$1}}
add_header = X-Sender-Domain: $acl_c_sender_host_domain
