Outlook is notoriously dumping reference headers in favor of some M$-only
reference-alike headers. [besides all those ugly "AW:" or "SV:" stuff
added to the Subject]
For German readers using Outlook 2000:
Go to Extras -> Optionen -> E-Mail-Format
[SNIP]
This will turn on Re: for replies and not those ugly AW: and so on.
Correct, but Outlook will still destroy the threading information, which
is more annoying than the localized version of "Re:".
This is why I use Mozilla over Exchange for this mailinglist... works
perfectly I hope. Nobody complained so far..
