Our IMAP mail servers now support the IMAP LIST Extension for Special-Use Mailboxes. That means we send hints to your IMAP mail program suggesting it should store copies of sent and deleted mail in the “Sent” and “Trash” mail folders on the server, rather than a different location the program might randomly choose.
Without the hints, some mail programs default to storing copies of sent and deleted mail only on your local computer or device. Those copies can’t be seen by other programs or devices, and they aren’t saved in our backups. You could always change that manually, but with the hints, some mail programs — particularly macOS Mail and iOS Mail — will now automatically save the mail to server folders with no extra configuration needed. The copies will then be visible on all the IMAP devices you use, and they’ll be saved in our backups.
What if I don’t want my mail program to use these folders?
If your program doesn’t offer that feature, another option is to delete the “Sent” and “Trash” server folders from your mailbox (or ask us to do so). That will prevent any hints from being sent at all, making things work exactly as they did before.
This is fine, except that old versions of Adminer have a serious security vulnerability that allows “hackers” to take control of sites that use it. If you’ve put an old version of the adminer.php script on your site, then you never updated or removed it, your site is vulnerable to hackers. A couple of our customer’s sites have been “hacked” this way in the last week.
To make sure this doesn’t happen to more customers, we’re disabling any old vulnerable versions of adminer.php (versions earlier than 4.7) and replacing them with a link to this page.
If you try to use a copy of Adminer you’ve previously installed, but you get referred to this page, you should simply install a new version from the Adminer website. Be sure to keep it updated in the future (or delete it when you’re finished using it).
If you have a parked domain name on our servers that’s set up to redirect to another site, you can now use https:// URL addresses for the parked domain name and the redirect will work securely, with no problems.
Update August 21, 2019: The maintenance described below has been completed for all sites.
Over the next few weeks, we’ll be retiring some old servers and moving sites on those servers to new (often faster) ones. Migrating a site takes just a few seconds in most cases, so it’s likely that neither you nor your visitors will notice this happening.
If someone does view your site while it’s being migrated, they’ll see a maintenance screen with a link to this blog post, like this:
If your site is in the small minority that has a large database (more than a few hundred MB), the migration could take a little longer — perhaps a few minutes. We try to do migrations during slow periods for each site, minimizing the impact on visitors.
