(Get the code!)
My understanding now is that the resolver *tolerates* search domains starting with a ".", stripping it off. This is very visible in the code snipped posted by Sergio:
if (dname[0] == '.')
dname++;
and this is the reason "search ." is not really documented: it's not really useful as in practice it is not different from having no search domain at all.
However, given that "search ." is for some reason not that rare, I think it makes sense to make the postfix postinst script tolerate it. The fix only requires a small change in a regexp.
