Hi I'm trying to set up an environment using postfix without dns.
For hostnames the server will have only hostname01, hostname02 etc (i.e. not even qualified by .localdomain) At the moment it's not possible to change this hostname setup (because of 3rd party software) In my test environment, the postfix install doesn't complain, but in the production environment, I get the "unqualified host name (xxxxxxxx) unknown; sleeping for retry", *but* the mails get delivered OK. I'd like to try and get rid of these errors as, in the production environment it leads to a delay in starting up postfix and in sending the mails from each server to the central mail server. Below is all my /etc/postfix/main.cf contains: disable_dns_lookups = yes # stop postfix from checking mail.aliases alias_maps = hash:/etc/aliases #myorigin = $mydomain myorigin = $myhostname # appending .domain is the MUA's job. append_dot_mydomain = no myhostname = centos56-ian-test-01 mydestination = $myhostname, localhost.$mydomain, localhost [root@centos56-ian-test-01 ~]# more /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 10.255.xx.xxx kanshi kanshi.localdomain 10.255.xx.xxx centos56-ian-test-01 more /etc/aliases # Person who should get root's mail root: ian@kanshi As I say, it's not a non-delivery problem, it's a slow startup problem, which isn't important now, but might possibly be in the future. Any ideas would be great. Thanks Ian
