Fedora core 5 + ISPConfig are installed on the server. My server’s name is ns.nestor.org.gr . Using ISPConfig I create a new site ….. Hostname: www Domain:nestor.org.gr IP Address: 195.251.5.3 All the users that use outlook to get their e-mails before the new installation of the server used to give at outlook settings as SMTP and POP3 servers the name “mail.nestor.org.gr” . Now this doesn’t work and a solution is to give the IP address. How I can fix this problem and make the mail server able to bee seen as “mail.nestor.org.gr” ? Thanks in advance .
Add an A-Record for 'mail' in the DNS zone of the domain nestor.org.gr pointing to your server IP address.
