Our office recently moved to a new location thus having to get a new static IP address. Everything was working fine prior to the move.
1. We our mx records pointing to mail.companyname.com
2. The name record mail.companyname.com has been pointed to our new IP address.
3. All networking hardware remained the same it was just moved from one building to another.
but we are getting random emails that fail to send with the following error code:
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<mail.companyname.com #5.7.1 smtp;550 5.7.1 <firstname.lastname@example.org>... Refused - Please relay through your ISP mail server HOST static-11-111-111-1.xxxx.fios.verizon.net>
Any assistance is appreciated.
