We have email alerts set up. But we would like to set up our PRTG server to send text messages to our cell phones if our email server goes down. We use Verizon phones so we can email [email protected] and it will convert the email to a text message. However, when we test this, we just get the error "Error sending "Email": error: address blocked 0 0". I have tested the vtext.com address from my Outlook and it works no problem. Emails from PRTG to our email work fine as well. Is there somewhere in PRTG where I can find more info on this error?
