Help with error msgs not able to send text msgs

[imyers1313]

I need help!! For the past 5 mo I have sent text msgs to a cell phone by my computer. Sun morning I started to receive "550 relay denied" and Wed night now I am receiving, 554 the user doesn't have a vtext acct.
Does anyone know what is going on and how to fix it?? Thank you for any help you can give me. It will be greatly appreciated..

Do you use Verizon? If so, sign in to your "my verizon" online account and check your text preferences. You may have to to uncheck the box that said "block text messages from email".

Register HERE for a "my Verizon" account if you haven't already.

Please let us know if that works so we can help others.

Thanks!
