I think that's only true if you are running sendmail -odi (deliver interactively option). Smail does local delivery in the foreground and remote delivery in the background (dunno if that includes DNS lookups). Exim can't be told to do foreground deliveries while talking to an SMTP client, and qmail and postfix don't have the right architecture to allow it. This sort of supports my earlier comment about the design of mailers changing in this respect about 15 years ago.
