I have an installation with a lot of post offices. Inevitably, someone in one post office gets hacked into and that account used for spam which, in turn, causes the IP to be black listed until I can resolve it. Is there any way to specify an SMTP IP for outgoing mail on a post office basis so not everyone is hurt by this?

Blacklists look at the IP the traffic is coming from. Changing an outgoing port would not help you. About the only thing you would be able to do is add another IP to the machine if you have one and change the IP binding in the SMTP service properties.
Under the Servers branch in MailEnable Management right-click the localhost (what it says on my server) and select Properties. On the General page you can enable postoffice bindings and assign IPs per post office.
That sounds perfect. So I will be able to assign a few post offices to outgoing IP A and a few others to outgoing IP B?? That way is somehow A is added to a block list than it won't effect B? I am assuming I can assign multiple post offices to a single IP. Would be rather silly to limit this to just a 1-1 relationship.
