save $home/Maildir/.INBOX.intray.backup/
Now whilst this regular expression is quite convoluted even if I just
put $header_from: does not match "windows" it still doesn't match
Can anybody tell me why that's the case?
In my case I don't want to copy mail with foreign charsets etc into
the backup folder which is why copying it is conditional that it
doesn't match those patterns.
