[EXIM] Mail to host's literal IP

For some reason I can not get mail to the mail server's literal IP address
206.101.242.50. Here is my relevant config info:

local_domains = "sparrow.sanasys.com:sanasys.com:[206.101.242.50]:\
                 lsearch;/etc/exim/domains"
local_domains_include_host_literals = true

Mail addressed to this IP gives:

sparrow:/etc/exim# exim -d5 -bt nschuler@206.101.242.50
Exim version 1.73 debug level set to 5
probably Berkeley DB version 1.8x (compatibility mode)
lookuphost router called for nschuler@206.101.242.50: dns lookup:
route_domain = 206.101.242.50
lookuphost router failed
literal router called for nschuler@206.101.242.50: route_domain = 206.101.242.50
literal router failed
nschuler@206.101.242.50 is undeliverable:
unknown mail domain
