I was under the impression that google app's mail systems use of SPF http://www.google.com/support/a/bin/answer.py?hl=en&answer=33786 http://www.google.com/support/a/bin/answer.py?hl=en&answ... handled these types of problems well. I realize this first step only works for sending below gmail's per day send. My plan was to do the following: 1 - use google apps with SPF to ensure my general personal emails gets through 2 - use my web server's local SMTP to send my registration and other user demanded server sent messages. My plan was to add my server's SMTP info in an SPF compatible way (still don't know how to do this part.) 3 - use a service (mailchimp etc.) for newsletters. Can someone expand on this thinking? Particularly step 2?
