Andrew, We own a hosting company and recently switched to qmail from postfix for its better virtualization and better web based management tools. Checkout qmail toaster rpms at http://qmailtoaster.clikka.com/. Qmail has a strange source only license but the self building srpms make it easy to install. QMail is extremely good, it performs very well, it has a good attention to security and so on. We limit our attachments to 10mb and have had no problems in that regard. Sendmail is awful from a performance, configuration, security standpoint. It has a terrible record on all counts, I find it very hard to justify its use to day in the face of postfix and qmail. Sincerely, David Uhlman CTO 50km Inc.
