    At 00:00 UTC on 29 May 2021 we will begin blocking unsecured outgoing SMTP connections from Opalstack web servers by blocking outgoing port 25 in our network firewalls.

    If you are running an application on an Opalstack web server that makes SMTP connections to external SMTP servers then please ensure that your application is configured to connect securely over port 465 or port 587.

    Applications that use the native PHP mail function and other apps that use sendmail directly on the server will not be affected by this change.

    2021-05-29 00:20 UTC The new firewall rules are now in effect on all servers.
