We have been using the tmomail.net e-mail to SMS gateway to send notifications for voicemails received by our corporate PBX. Sometime within the past few days, these messages started to get blocked. We are getting a 550 failure code with a "rejecting banned content" description. There have been some other threads that mention that we can get our domain whitelisted. srickar has helped others in the past with this, so I have requested to follow him so that I can direct message him our details. The other threads have been closed, which is why I have started a new thread. The most recent thread was answered with a solution to use an SMS short code to send out such notifications. This is probably not an acceptable solution to most customers on this forum, as it costs $1000/mo to maintain a short code.
