In some cases the server or proxy does not resolve macros in host interfaces

host name:         127.0.0.1
host visible name: dns

Zabbix agent main interface:
IP:  {HOST.HOST}
DNS: {HOST.NAME}

Action message:
{ITEM.NAME} : {ITEM.KEY}

Item name:
item {$M} $1 $2 $3 $4 $5 $6 $7

Item key:
item[{$M}, {HOST.CONN}, {HOST.IP}, {HOST.DNS}, {HOST.HOST}, {HOSTNAME}, {HOST.NAME}]

Generated message:
item host-macro host-macro {HOST.HOST} {HOST.HOST} {HOST.NAME} 127.0.0.1 127.0.0.1 dns : item[host-macro, {HOST.HOST}, {HOST.HOST}, {HOST.NAME}, 127.0.0.1, 127.0.0.1, dns]

Expected:
item host-macro host-macro 127.0.0.1 127.0.0.1 dns 127.0.0.1 127.0.0.1 dns : item[host-macro, 127.0.0.1, 127.0.0.1, dns, 127.0.0.1, 127.0.0.1, dns]

Poller can't process items with such interface:
Get value from agent failed: gethostbyname() failed for '{HOST.HOST}': [1] Unknown host
