Post How to transfer mail server(all mail account, message of all user) to another machine


I have a Mail server, containing 70+ mail user and many personal mail messages of all mail server users. But the problem is my Machine is not upgraded it is Pentium #3 and slow. Therefore I have to change the machine by high performance & speedy computer like Core to due.

Now I have to transfer mail server (all mail account, message of all user) from slow machine to high performance machine.

My existing Mail server have Fedora 9 Install, MTA is Sendmail and user are use there mail by browser.

Please help me as soon as possible.
I am requesting the Linux Mail Server Expert.

I'm no Linux Mail Server Expert but if the webmail setup is the same and the user Id's (UID, GID) are the same, then (making backups and) copying users mail configuration and mailspool files and mailbox or maildir structures should work. If you don't trust things you could test it yourself easily by (making backups and) copying files over for one user?

If both servers use the same distribution and system version, then replacing /etc/passwd and /etc/shadow on the new server with the old files will give you the same UID/GID numbers. The documentation of your mailserver should explain where and how data is stored, so simply copy these as well. As for the /home directory - copy that one completely. If your home directory is on it's own hard disk, then simply add the old hard disk to the new system.

A lot of possibilities - be creative.
