There are several reasons why emails might stop working. To start the troubleshooting process, check the following first:

  • Your hosting or email hosting plan is active

  • The domain is registered and activated

  • The domain has the proper MX records added. For better deliverability, it is recommended to add SPF and DKIM records as well. If your domain is pointing to Hostiner by nameservers, all the required email records are added automatically

  • You have created the email account

  • Your email services are enabled


  • After activation, a domain can take up to 24 hours to start working

  • Any changes on your domain's DNS records require propagation, which can take up to 24 hours to complete

  • Email messages can take up to 15 minutes to be delivered

Specific issues

If your email is still not working after ensuring that the previous requisites are met, check the following table for possible reasons and solutions to the most common issues:


Most common reasons and solutions

Cannot send or receive emails

Can send but not receive emails

“Your message wasn't delivered to (address) because the address couldn't be found or is unable to receive mail” error is shown

  • Mistyped or inexistent receiver's address. Double-check for typos

  • Incorrect MX records on the receiver’s domain. The receiver needs to fix the MX records on their side

The email client/plugin doesn’t work, but emails work on Webmail

PHP/SMTP file for sending emails doesn’t work

Double-check the file and make sure the parameters are correct

Emails are disappearing

  • There is an email forwarder active where the option to leave a copy was not selected. Change the settings of the forwarder to leave a copy on the server

  • There is an email client set up with POP3. Change the configuration to IMAP or make sure to select the option to leave a copy on the server
