Below you can find a list of recommended DNS records. While some are mandatory for a mail server (MX), others are recommended to build a good reputation score (TXT/SPF) or used for auto-configuration of mail clients.
Name/Host | Type | Priority | Value |
Blank/empty or @ |
MX |
0 |
mail.op-email.eu |
autodiscover |
CNAME |
mail.op-email.eu |
|
autoconfig |
CNAME |
mail.op-email.eu |
|
Blank/empty or @ |
TXT |
"v=spf1 mx a -all" |
Note:
- @ is used in the above table to indicate the root/naked domain (domain.tld). If your DNS server/provider doesn't support @, you can simply leave the Name/Host field empty.
- The above TXT record is a simple SPF record that is used to only allow the Openprovider email server (the MX) and your web server (the A) to send mail for your domain. Every other server is disallowed (-all). If you need to allow mailing for the domain from any other sources/servers, please make sure to include the host/IP address in your SPF record.
