host_find_byname is an Exim function that finds an IP address from a
host name or an IP address. It calls the system function
gethostbyname(), from whose man page this is taken:
DESCRIPTION
The gethostbyname() function returns a structure of type hostent for
the given host name. Here name is either a host name, or an IPv4
address in standard dot notation, or an IPv6 address in colon (and pos-
sibly dot) notation.
No DNS lookup is involved.
