Hi there. Forgive me if this has been asked before, but some brief searching came up with nothing.

I'll be moving our e-mail services from an external host to my internal ZCS server in the near future and I've got a question on setup. Right now, our external host has separate incoming and outgoing servers: pop.duratechindustries.net and mail.duratechindustries.net. That makes sense to me considering number of clients. Is there any reason why I should do the same thing for my internal ZCS server, with my measly 60 users? For that matter, I've already installed ZCS and use a singular URL for both POP and SMTP; what would it take to split them up?

Thanks in advance!
