View page history... h1. Supported Standards This appendix lists national, international, industry and de-facto standards related to electronic messaging and for which support is claimed by Messaging Server. Most of these are Internet standards, published by the [RFC Editor|http://www.rfc-editor.org/] and approved by the [Internet Engineering Task Force (IETF)|http://www.ietf.org/]. Standards for documents from other sources are noted. h2. Messaging The following documents are relevant to national and international standards for messaging (these tables are generated automatically, so please add a note to this page rather than editing them directly if you find an error). Software compliant with older IETF RFCs is usually compatible with newer RFCs unless the protocol version changes. Where the table mentions a newer version in parentheses and that version is not listed in a separate row, we have not made a complete assessment of compatibility but are probably compatible with the new version unless otherwise stated. Newer versions of IETF specifications often drop features that were optional, rarely used or problematic. If we implemented features of note that are present only in the older specification, the older specification is listed on a separate row in addition to the parenthetical mention. Features with status "Experimental" or "Work in Progress" may be changed incompatibly in a future version until the specification has settled. Features with status "De Facto" may not interoperate with all software as interpretations of the de facto standard may vary. h3.
