It's mainly for "vanity" virtual hosting so our clients can be assured they have their own fully branded mail service. More importantly, with the -o myhostname=domain1.com they can fully pass any hardfail SPF test, and of course if they get on a blacklist it does not affect other clients on the same server so there are tangible benefits to this "vanity" branding. > but if there's a business reason why you would need this, have a > look at the multi-instance documentation; > http://www.postfix.org/MULTI_INSTANCE_README.html We want to run 100s, if possible 1000s, of these setups on a single server and I fear (but no evidence) that the above example of separate postfix processes won't scale. That's aside from the configuration nightmare compared to managing a single config file. Is any here using a similar method to what I outlined?
