We include with any web and reseller hosting plan our e-mail servers for free. We manage high-quality IP reputation mail servers to increase the chances that your e-mail arrives in the inbox rather than the spamfolder. This article explains how you should configure your SPF records to improve the e-mail delivery.
By default, we have configured your domain already. However, if you have updated the SPF by yourself, or, when you use an external DNS system, you can use this article.
Here is an example SPF record. You can find the current SPF record with the DNS settings of your domain.
"v=spf1 a mx include:domain.com ~all"
Note: you are required in cPanel and DirectAdmin to use quotes. You should not use quotes in Plesk
To add support for our mail servers, simply add include:mxo.ispnoc.eu to the SPF record. Note that you should add this before the -all portion of the SPF record:
"v=spf1 a mx include:domain.com include:mxo.ispnoc.eu ~all"
It can take up to 24 hours until every device on the internet can find this new setting. After this, your e-mails have a higher chance to arrive in the inbox.
