It is a very important situation. Consider the fact, that a large mail
hoster will quickly queue thousands of mails to the same MX of another large
email provider.

performs pretty well, if you configure it. Not sure about postfix, qmail is
also doing quite well, with the exception of limited concurrency in the
unpatched version.
