Azure VM IP blocklisted

Copper Contributor

Hi all,

We are using azure VM for hosting web application. This applications send emails to users. The IP of the VM got blocklisted. When searched found that


"SMTP servers should be configured with correct forward and reverse DNS and HELO/EHLO values."


Can you please help where to configure these values

1. Domain hosting server 2. email server 3. Azure VM

We are using godaddy mail server (and this is configured in SMTP of IIS) to send emails.

Do we need to map domain  name in Azure VM(public ip) configuration of DNS ? will this resolve.


Thanks in advance

Cannot get this, are you pointing to godaddy SMTP server through IP address, or FQDN?
