Well, it's what I do to separate "outgoing" from "incoming" and
allow/impose separate rules, respectively. "It works for me".

I don't have any content filter in main.cf, I have proxy filters (-o
smtpd_proxy_filter=whatever) in master.cf. if I *did* have any content
filter, it would be in master.cf, anyway, since it's instance-dependent.
IOW set it for each instance in master.cf, not in main.cf.

Next thing is: Get yourself a test server (can be an el-cheapo
something), with its own domain and static IP, mail server service
guaranteed (my dialup one costs me ¤16 per month from Demon Internet in
Holland). There's nothing like it.

Separate instances are not necessary, separate listeners are.
