Outlook / outlook express read confirmation, some server generated messages (ie. dsbl removal confirmation), and I don't know what else. I suppose also meeting request via exchange, but I don't find the papers where I read about it. + many misconfigured servers that don't want bounces when they spam to the wrong address that "Message you sent was blocked by our bulk email filter" but that's not a legitimate use. By the way, how did you configure your 'proper vacation autoresponder' to be sure that you never send your messages to the wrong person ? ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
