We are a current rackspace customer and it's been YMMV with them.

We had a particular project that we needed to use the VPS for and noted the page on the SMTP policy. The sales staff were all over us with emails and follow ups but when we posed the question regarding something specific with the SMTP policy (pointing to the particular page) they went silent. No answer, no follow up no reply to our follow ups.

Sent an email to the page that says "if you have any questions write here" and got a link back to that same page (iirc or something literally that worthless).

The lack of follow up (for an important issue) and reply ( to questions) made it a non-starter to use Rackspace for this purpose.

Found it. So in other words we sent an email to abuse@rackspace.com. with a question (per what the page says) and got this auto response:

THIS IS AN AUTOMATED-RESPONSE

Please read carefully! This may be the only response we send you.
