A consultant, long gone, set up postfix, dovecot, amavisd and squirrelmail for my wife. It works fine but my wife wants to change the server name from old.com to new.com so the name is more appropriate for her business. My approach would be to use sed to change all occurences of old.com to new.com. Specifically, I used grep to identify the following files where I should make the changes.
/etc/postfix/main.cf /etc/dovecot/dovecot.conf /etc/squirrelmail/config.php /etc/amavisd.conf /etc/sysconfig/network (change host name) In addition, there would be an MX record for mail.new.com pointing to the IP of the server.
My question is, will this work or will I corrupt my email server? If I mess it up I can always restore it to the original.
- Maybe check /etc/hosts.
- What about the old domain ? You may not be able to receive e-mails for
it. You can think about add the new.com in parallel with old.com on the same server.
Check also your hosting name (e.g. httpd service).
BTW - the MX entry can still have the old name and accepting new.com-mails.
Furthermore - take care if SSL/TLS is in use. Certificates are connected to domainnames.
