Issue: When I send emails to Microsoft mail sites (ie: hotmail.com, live.com, outlook.com, etc), I receive an error response stating "Unfortunately, messages from 220.127.116.11 weren't sent. Please contact your Internet service provider since part of their network is on our block list."
Problem: At some point, the email server was placed on a block list for Microsoft.
Resolution: The mail administrators are working with Microsoft at this time to remove our IP from their spam block list. This is a very long and arduous process we have to observe before it'll be resolved. Until then, you'll need to use alternative mail servers to communicate with those using Microsoft as their email provider. We apologize for this inconvenience.
