I mean exim spends time on sorting the recipients and messages,
qmail just sends them. And if you have thousands of recipients you
have to spend a lot of time sorting... And once exim has them
sorted it can't save all bandwidth it would like, because the
number of "RCPT TO:" commands in a smtp connection is limited to
20.
