I recently got a message from a developer who had put his own e-mail header "X-Message:" for special private needs of his application. However, this user had found that this caused confusion to MS Outlook, which also seemed to be X-Message:" for its alternative uses. Perhaps the DRUMS document should be modified to indicate that "X-"headers should have the format "X-<vnd>-header" where <vnd> might for example be MS, so that future Microsoft private headers should be for example "X-MS-Message" instead of just "X-Message". This might avoid future similar problems. I know this is not 100% safe, to get that we would have to adopt object identifiers, which is probably not so popular, but it would at least reduce the risk of this kind of problem a lot. Perhaps add the following text to the end of chapter 3.6.8 in draft-ietf-drums-msg-fmt-07.txt: Private, non-standardized optional-fields should contain the acronym of the vendor in order to avoid the risk of two vendors using the same field name for different purposes? ------------------------------------------------------------------------ Jacob Palme <jpalme@dsv.su.se> (Stockholm University and KTH) for more info see URL: http://www.dsv.su.se/~jpalme
