Best practice for mailserver setup

  • Posted September 11, 2014

Hi,

I followed an tutorial about setting up a mailserver.

I have setup the following DNS records for my domain in DO`s DNS manager: Mx 5 mail.mydomain.com. Txt @ “v=spf1 mx -all” A mail.mydomain.com. IP.AD.RE.SS

This should setup mail.mydomain as mailserver right? I am using virtualmin which has postfix mailserver running.

This is not (yet) working for this domain, but I got it working on another domain, so that does not really matter for now. What matters is that i`m wondering if this is the ideal configuration for a mailserver. Am I not missing a few backup TXT or Mx records?

What are the best practices, DNS records or postfix tips to setup mailserver for reliable e-mail sending and receiving? Also, what are the pitfalls of my setup? I use dovecot for IMAP mail sending and receiving.

I`m totally new on this so hopefully someone can help.

What is essential that I can setup a mailserver like mail.mydomain.com, or mail.myserverfqdn.nl , something like that.

With this configuration you are able to send mail for all servers in the world :)

remember that your vps name need to be the same of your mx name: mail.mydomain.com. When you have your vps name as your mx record name, your PTR record on DO dns servers answer with “mail.mydomain.com”, this is essentials to your server work perfectly.
