I don't believe it is "totally useless" to use separate instances for distinct services. Configurations can get complex. Outgoing mail may be handled differently than incoming mail. Using multiple instances can simplify the task. While it may not *work* in this case, using multiple instances for MX and submission services is far from *useless*. > >> mail_version = 2.8-20100707 >> > > UNSTABLE. > sheesh. > Plenty of people would argue that Postfix experimental releases are quite stable. In this case I would like to test and make use of postscreen.
