downtime notice

We're going to take the antiflux.org server offline tomorrow to shuffle our disk configuration.

Date: Thursday, January 9
Time: 9:00 pm PST
Duration: about 30 minutes

All services including email and web hosting will be offline during this time. Incoming email should be queued on the sender's side and delivered once we're back online, so nothing should be lost or bounced. We'll post a notice at http://antiflux.blogspot.ca/ if something goes wrong.

mail server now checks FCrDNS

I've noticed a lot of spam lately, so I added reject_unknown_client_hostname to check FCrDNS on incoming mail connections. According to the logs, it has already blocked a lot of obvious spam.

If you know of any legitimate incoming mail being bounced back to the sender with a message like "450 4.7.1 Client host rejected: cannot find your hostname", let me know.

disk errors affecting mail

The disk hosting email has been reporting errors, so mail delivery is currently offline while we migrate to a new disk.

Update 2019-08-20: Mail has been migrated to a different disk and has been up since Friday but there are still problems with the disk. We're getting a new disk tonight to fix the remaining problems. This will involve some downtime, probably a couple of hours.

Update 2019-08-20 (2): We're back up with the new drive. Mail is still offline while everything is migrating.

Update 2019-08-21: Mail is back online. Everything should be working now. Let me know if you notice any further problems.

drive failure affecting mail

The hard drive hosting mail suffered a hardware failure around 1:30 am (Mountain Time) on Saturday, December 1. We were able to restore data from the previous backup and mail delivery should be working again now. Impact:

  • You may have lost messages delivered to your inbox during the window between that backup and hardware failure. Messages moved from your inbox to another mail folder were not affected.
  • Mail sent between the hardware failure and us getting back online would have bounced back to the sender or been queued for later delivery.

Let us know if you notice any further problems.

Let's Encrypt

I switched our SSL certificates over to Let's Encrypt. This should fix the recent problems with macOS and iOS complaining about the certificates we generated with our own CA. This covers: Let me know if you hit any problems or have any other SSL vhosts you'd like to switch over.
