Sometimes a domain takes up the majority of the bandwidth to send emails at the expense of other domains. This in turn, resulted in delays of email delivery. Using Distributed Intrinsic Scheduler, MailNow! 5 solves this problem by employing a smart algorithm and a fair policy – so emails from each domain are treated in a different queue and serviced by doing a round inspection. This ensures that emails from all domains are treated equally, thus prevents delay in email delivery.
