Keep in mind that this SMTP transaction with Exim has 60 RCPT TO
commands and responses which is probably where most of the time is
spent. If Exim is doing DNS verifies on the recipient domains during
the incoming SMTP, 0.5 sec per recipient may not be that bad.
The solution is to not do DNS verification on mail from localhost. See
