I’m new to mailinabox and I’ve really enjoyed the experience last three weeks for my personal and professional use. I’ve been able to get my Digital Ocean provided IP address off several blacklists, including Proofpoint.
One of the areas that has stumped me is that I had emailed a company through a contact form on their website. In their response, I see the subject line included [CAUTION SPOOFING] which carried over from the first email that landed in their inbox.
What can I do to prevent this in the future. I want my email setup to professional and seamless. What information would I need to provide this community to help remediate?
