As I look at this thread history and your log I suspect but cannot fully verify that all you are seeing is a side effect of DHCP or Thunderbird. Some users may may be seeing two layers of DHCP.. further complicating things. DHCP can set a long list of things from timezone to hostname lots more ending with an IP address. You can look at your distro documentation or the URL in your log file "http://www.isc.org/sw/dhcp/"; to see what hooks DHCP has to setup a system. DHCP is run early and is designed to change some things as root. You can configure the client to ignore, override etc most of them. Another external input is the mail message that Thunderbird is replying to. In general a graphical email tool will transparently pick up the character set of the message you reply to. Some HTML/XML/RichText messages can have multiple character sets in a message that includes previous messages in this and that language/ character set. The most common reply hook is to "reply in kind". If you send me html mail I would assume that you are OK with HTML and if you reply to a 'text' email then a reply in the same 'text' mode is apropos. Also mail transport agents are getting character set aware. In a global world host names and user names used for email delivery are no longer restricted to the classic 7bit ASCII character set. Depending on the email message structure you may see interesting things in Mail headers or MIME attachment headers. I said "Most ISPs can be trusted!" while true is still subject to the normal problems of individuals exceeding their limits and bounds. Further ISPs AND their employees can be subject to pressures from all ends, legal and not legal. Because of this it makes sense to exercise caution. -- T o m M i t c h e l l Found me a new hat, now what? -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
