[tor-relays] Outbound Address differing from exit address

[jason at icetor.is]

Greetings all,
I'm in the process of setting up a few Exits on a Cloud provider here in
Iceland (one that I used to work at actually). Since they use Cloudstack
it means each address per account gets multiple inbound address per
instance and share the same address for outbound traffic. I'm worried
that abuse notices will be coming in for this outbound address even
though I've got 80 on the exit node's IP showing the standard Tor Exit
disclaimer. I've tried to set OutboundBindAddress to the outbound IP
using arm but this just causes arm to complain about:
"[WARN] Error binding network socket: Cannot assign requested address"
Any advice would be appreciated.
