I have gigaPros too, for stand-alone RMS. One thing that's always worked is the ray apps. Very happy with them. I never speak to them after the setup is finished. It's NICE to not have to be running after your hosting company!

I have Dreamhost for the rest of the house, and will say this: they have that f_Url open thing off. It didn't bother my D6.x installs, but I hear that's probably my problem with not being able to register my D7, the phone home thing isn't going thru. (if anyone has see more any other theories on registering my licence, I'd love to hear them!)

Also, Dreamhost has an option for your domain mail via google apps if you want to use it. I do, but it's a real bear to set upmailing out from software packages. It might nt be a problem for most, but when I have an error, that one added level of settings makes it harder to trouble shoot.
