You can safely and easily run Postfix on your existing application servers. It's very efficient, especially since you are only sending mail out, not accepting incoming messages. (Presumably you'll set the Reply-To: address to a working mailbox at your company.) There are two tricks to sending mail on your own: reverse DNS and (increasingly) SPF headers. You can get your upstream ISP to provide reverse DNS for your IP addresses -- the name doesn't have to match the hostname of the server, but it does have to look like a static assignment (so servers don't think you're sending from a home network). You set SPF records in the DNS for your domain name, and they should assert that mail from your domain is allowed to be sent by your servers.
