thats going to be the way to go to avoid any problems, its never been a
problem anyway for the servers I manage, but currently running half only
as  postix's virtual, nearly 2 weeks now? no problems, so if we need to
go all postfix on delivery there will be no issue.

I recall copious amounts of it, I'd certainly never call it "some",
though, this was a few years back, if you have cleaned up your users
(yes I too know all well there will always be idiots having also managed
a DSL based  (read as: windows infected malware weenies) ISP) then I am
prepared to suspend those rules, as you know, when a domain has problems
and only gets bigger over time, its harder to imagine there will be less
of a  problem, but, that said,  a leopard although rarely changing its
spots, can occasionally do so.

Our users have also become accustomed to the fact that we operate as,
protecting the majority, not letting any minority dictate our decisions,
we'd rather have 1K peaved off users for not getting mail, than 100K
peaved off for being constantly spammed.

Thats one thing I was not able to reproduce, but, again, not having a real imap userbase we wouldnt see issue, 
as most users use pop3 only, if we changed policy and if users actually used imap, perhaps we would see a degredation.
