It's not prejudicial. I do not wish to start yet another MTA flamewar,
but you can't deny Sendmail's poor security, design, performance, and
complex configuration. The poor security history is there, the poor
funnel design and conf files that require a scripting language are
obviously ugly. Sendmail is often replaced due to performance concerns
alone. There are much better alternatives. qmail and Postfix.
