New Email
Hello all, I need some help understanding the correct way to configure my HELO IP to ensure email delivery.
We have a dedicated SMTP server hosted offsite and we use a third party email marketing platform to send emails. The hosting company has control of our domain, and set up the SPF and DKIM records and both pass. I work remote, and often send campaigns from either home, or another office. The email marketing software by default uses the IP addresses of the internet connection I am using for the HELO.
Based on what I read, incoming servers look at the HELO message prior to accepting an email and perform a reverse dns on the senders domain, to ensure that IP in the HELO matches domain. To further ensure delivery, I had the hosting company add both domains to the SPF and DKIM records.
The email marketing platform allows me to change the HELO field, so I have the option to use either the server IP, home internet IP, or work office IP. I am curious as to which IP to use in HELO for maximum delivery rate.
As an example, I am going to show you a sample email header to illustrate. For this example, assume the Server HOST IP is (XXXXX), the office using port 25 (YYYYY), home using port 587 (ZZZZZ).
Sent from Home
Received: from unknown (HELO ZZZZZ) (john.doe@example.com@ ZZZZZ)

Since the HELO us not related to the host IP, does this increase the chances of being sent to junk?
