I use Sylpheed-claws for mail (v8.2 package version) and I receive this weird message from the local mailer daemon that I never got in v8.1: 'This text is part of the internal format of your mail folder, and is not a real message. It is created automatically by the mail system software. If deleted, important folder data will be lost, and it will be re-created with the data reset to initial values.' What's with this? I do have root local mail sent to me (saves logging in as root) but I never had this behaviour in v8.1. I get hundreds of emails a day, many of which I delete as I read through because the thread does not interest me and it is very annoying to have to avoid this message. Can I filter it out of my inbox? I know nothing about it? It's only a minor annoyance but advice as to how to avoid it would be nice. Paul.
