  • SYSADMIN: Started sending email through a fourth email server.

March 5, 2024

  • CHANGE: Switched DKIM signing to a 2048-bit key, as required by iCloud and others.
  • CHANGE: Strip any 'ARC' related headers from incoming group emails.
  • BUGFIX: In some instances, when uploading a directory to the Files section, one of the files would be rejected if it was at the top level.
  • CHANGE: For group messages, we now change the Date header to be the current date/time when we send the message to members. This is because some mail servers will reject messages with a Date that is too far in the future or past. We do not modify the Date header as it is stored in the archives.
