Friends, I have a good qmailtoaster server that I intend to switch out with my present mailserver. My present mail server is a linux machine running postfix. my dns points mailhost.mydomain to my present mailserver
I would like to do a switch that could be as simple as changing the hostname & ip num on both these machines - just flip them my present ( postfix ) email server : cat.mydomain.com , 208.nnn.nn.101 my future ( qmailtoaster ) server : dog.mydomain.com , 208.nnn.nn.100 can it be as simple as changing the host name and ipnumber on my future server? and I would just turn the older ( postfix) machine off. OR isn't the host name ,as it existed at the time of the qmail-toaster install, referenced in various places in mysterious QmailToaster Files. And if I change it ( host & ip num ) will I just break it? - because some QmailToaster file is expecting something diffrent. If true, is there a script that will march about and change the "...mysterious QmailToaster Files ..." In other words which is better: change my DNS and wait for that to percolate ( and/or maybe do some arp cache clear ) or flip the machine name , num. ( simple, but I think it will not work ) Thanks jim
