<domain *>
.....
    use-starttls  yes
    require-starttls no
</domain>

will have PowerMTA use STARTTLS on outbound connections when the remote site supports STARTTLS, and will not use it when the remote site does not advertise support for it (opportunistic STARTTLS).

Is there much performance overhead for this?

Not much, just some cpu usage that cannot be avoided.  Whether it will be noticeable to you just depends on your system, volume of email, cpu head room, etc....

Has anyone noticed enabling this having any affect on deliverability? More trusted perhaps?

Since spammers are usually the first ones to do/try these things, I cannot imagine that it would offer any real deliverability benefits whatsoever.

I dont believe this would have any affect on delivery.
