The original hostname of the iredmail server was mlr.freesend.us. I changed the hostname to freesend.causeaction.com. After setting up DKIM DMARC SPF and MX records I tried sending just 1 email to my own Office 365 account. It was bounced by MSN because the from server was mlr.freesend.us and no longer matched any of the IP addresses. Nad I see thsi on the bounced email notification.

This is the mail system at host mlr.freesend.us.
I thought that all email would be sent from freesend.causeaction.com now that the hostname is changed. The bounced email was sent from the postmaster@freesend.causeaction.com also. So why did this happen and what shall I do to fix it? Thank you
