I just wanted to give everyone a heads-up on the antispam policies of SprintPCS, so that you will know what to expect if you start getting blocked by their mx.messaging.sprintpcs.com mail servers.
As a non-sprint-related side note, I know of somebody whose AT&T Wireless phone service was rendered completely unusable by incoming spam via the email-to-SMS gateway. The typical rate was one message every 30 minutes, the only solution offered by customer service was to change the phone number. Has anyone ever encountered spammers doing a dictionary attack (emailing all 9999 phone numbers in a NXX) via email-to-SMS gateways?
