Websites running old versions of web applications are moving to new infrastructure. The old web applications are containerized with Docker to enhance stability.
However we strongly recommend upgrading the web application and move to latest hosting platform Micusto Cloud. Also, note that continued use of old web applications will cause a restricted environment, e.g. forced use of SMTP AUTH instead of the PHP mail function which will be deactivated.
The use of PHP mail function will no longer be possible since it's the primary cause of spam abuse.
We recommend using SMTP AUTH to send out mail from website. Even old web applications support SMTP AUTH and configuration is made in core application or a plugin/extension.
Contact our support if you need help with SMTP AUTH, upgrading web application or moving to Micusto Cloud.
Mail accounts on old web servers are moved to new mail infrastructure with better spam filter and antivirus. See new setup information here (in danish).
