we have a server (debian) running apache with several virtual hosts
We have recently changed one of the virtual hosts ip address
Now when we send an email from the site with the new ip , the email is received by a different domain
email sent to email@example.com is received by firstname.lastname@example.org
both abc.com and xyz.com are hosted on the same server
Both used to have the same ip and the email was working fine.
The problem started after abc.com was set to have a different ip.
