Is Gmail rejecting your emails?

If you've recently started to receive error messages when sending emails to Gmail addresses, it may be due to a lack of SPF or DKIM authentication for your sender's domain.

SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are methods used to authenticate your emails, ensuring they're not flagged as spam or rejected by the receiving server.

The error messages you might encounter look like the following:

<example@gmail.com>: host gmail-smtp-in.l.google.com[142.251.9.26] said:
    550-5.7.26 This mail is unauthenticated, which poses a security risk to the
    550-5.7.26 sender and Gmail users, and has been blocked. The sender must
    550-5.7.26 authenticate with at least one of SPF or DKIM. For this message,
    550-5.7.26 DKIM checks did not pass and SPF check for [example.com] did
    not 550-5.7.26 pass with ip: [46.183.139.199]. The sender should visit
    550-5.7.26  https://support.google.com/mail/answer/81126#authentication for
    550 5.7.26 instructions on setting up authentication.

For domains managed at Gigahost, enabling SPF is a straightforward process:

  1. Log into the Gigahost Control Center.
  2. Click on the "Domains" section.
  3. Select the domain which you're having trouble with.
  4. Click on the "DNS" tab.
  5. Scroll down and select "Gigahost SPF protection" from the dropdown menu.
  6. Save the changes to update your DNS settings.

Note that it may take some time for the changes to take effect everywhere, but after a few hours you should be able to deliver emails to Gmail addresses.

If you encounter any difficulties during this process, please don't hesitate to contact our support team.

PHP 8.1 and 8.2 are here!

PHP 8.1 and 8.2 are here!

We are happy to announce that both PHP 8.1 and 8.2 are now available at Gigahost!

PHP 8.1 is a major update of the PHP language and contains many new features, including enums, readonly properties, first-class callable syntax, fibers, intersection types, performance improvements and more.

PHP 8.2 is another major update and includes features such as readonly classes, null, false, and true as stand-alone types, deprecated dynamic properties, performance improvements and more.

Since PHP 8.1 and 8.2 are major releases, upgrading may break some web sites. So make sure to test your site when changing to one of the new versions. On Gigahost, you can change the version for each domain name, and always revert to the earlier version in case something doesn't work out.

The PHP version can be changed in the Gigahost Control Center by selecting the domain name and then “PHP version”.
