Hi all,
I have the following problems when our colleagues try to send out emails to their receiptents. It is also reported from the reciptent that there's a reverse DNS problem, is it our email server needed to be configured with some settings ? Please give me a hand steps by steps as I really new with the server configuration. Now I just change /etc/mail/access and use our ISP provided SMTP for the solution, but it seems not ok.
Thanks
Keith
