I've once noticed that this did indeed help, yes. But in my case it
was sendmail that complained it didn't find the onw host. I forgot
the details, but i think the /etc/hosts part of the resolver library
is broken with this. Ah, yes, i remember: sendmail apparently tries
to lookup "${hostname}.", i.e. it calls gethostname(2), and appends a
dot to force DNS to not use the search order. The /etc/hosts part of
the resolver library cannot handle this unless the host is listed with
the trailing dot in /etc/hosts. I think this is a bug, and this part
of the resolver library should just remove a trailing dot, to be
(bug-)compatible to the DNS part.
