Aside from the customer service perspective, you hit on something else very important: Road use. Many of our customers are constantly on the go, so sending outbound through our servers keeps them from having to change their outgoing SMTP server every time they settle in to a new location.
There's also the benefit of using SPF to eliminate spoofed mail from customer domains. We receive a lot of spam with forged addresses from the customer's domain. Using SPF we can say that mail from a particular customer domain should only come from our servers. That not only serves to block all forging mail (spam and virus) from customer domains for us, but also for all other mail servers that check SPF. So, we eliminate forged mail from our customer's domains for us _and_ everyone else who checks SPF. If everyone did this there would be no more forged mail.

This save you bandwidth, processing, etc... *********** Two reasons for me: less technical support and more control. It is a lot easier to give client one set of instructions. It doesn't make any difference if they are on the road or setting up a machine at home or the office - the instructions are the same. When I was having clients go through their own ISP, I was constantly dealing with tech support issues having to do with their ISP. Now I could have just said, "it's not my problem, call your ISP", but I don't like to do things that way. Even though it cost me bandwidth, I also like keeping on top of what my clients are doing. This way, if one of them gets infected with a mass-mail virus, I can be proactive and get them sorted out for example.
