I would like to whitelist a range of ip addresses (will be provided by me).
Also, I need to create feedback loops for ip addresses\domains - in case emails won't arrive to Hotmail, Gmail, Yahoo etc (inbox)
you will need to contact the above directly and make sure that whatever is sent, gets to the inbox.
We will start with a pilot of ONE email\domain. If everything goes well, we have many more!
If you have the skill, please contact me.
