Hello,
Seems like another problem with my recent migration to 11.09 from 10.4.x
Customers are having email rejected because Postfix is attempting to send using their website ip, which is shared. In their DNS I have my email server listed as their MX. It is on a completely different dedicated ip address. Checking maillog I see dozens of rejections all with shared ip addresses of various hosting customers. None of these people have their own mail server and use mine by default.
Anyone know if this is a bug, or configuration mistake? My email server should be sending out with the same ip address as eth0 shouldn't it?
Thank you
