Well, the only performance that makes sense for a MTA is the throughput. In fact that is the performance you have to have in mind dimensioning a MTA setup. Unfortunately there is no real statistics about that available. It would also be somehow hard as it depends on the internal processing. So naturally the throughput would be lower when doing spam checking as it would be without. > Would anybody be willing to share performance stats? > (In a first step: submit the results from a tailored eximstats output?) Well, some time ago, I was implementing a setup for University Zürich. While taking mails it does Spam and two virus processings (with some other stuff). It was capable to manage a volume of up to around 5000 mails per hour per box without to much troubles. That was in 2012... Bevore going live, I did tests with around 4000 mails an hour.
