This is my first shot at setting up a server / mail server and am hoping I can get some guidence...
I've followed instructions here: https://www.vultr.com/docs/simple-mailserver-postfix-dovecot-sieve-centos-7
to set up email server.
Is this complete list of tasks needed to get server configured or more needs to done?
How do I set up SPF and DKIM?
Where can I find IMAP and SMTP settings?
Where can I find MX records to point to?
Also, what the best way to create a snapshot/image of this server so I can save time when launch this for other clients in the future?
Help is appreciated.
