EMails to @vtext.com blocked all of a sudden.

We have a server that hosts two applications that send emails for texts to subscribers of our service.   We changed nothing on the server and all of a sudden, texts to @vtext.com are no longer received.  SMTP logs show the message going to txslspamp3.vtext.com.  Other carriers are fine, normal emails are fine.  This only began in the last few weeks.

Tried a whitelist request with verizononline.net and they say our IP is not blacklisted, so I am guessing vtext.com maintains a separate blacklist.   As a note, we have emails sent from 2 different domains on the server and one of them has been sending texts for over 2 years successfully before late Jan/ early Feb. How can I get our server on vtext.com's whitelist so our customers can received their requested updates.

Wbadgett,


Let's get those emails flowing on the right path.  We all rely on our emails to accomplish our daily tasks.  What email provider are you using?

For these processes, we are just using the server’s IIS SMTP service. We are not relaying thru any other service. 162.42.192.64 is the server address that is being blocked.

Here are the logs from the smtp to see where it is connecting:
