Title : Advice for Safe Handling of Malformed Messages Author(s) : Murray S. Kucherawy Filename : draft-ietf-appsawg-malformed-mail-02.txt Pages : 16 Date : 2012-05-19 The email ecosystem has long had a very permissive set of common processing rules in place, despite increasingly rigid standards governing its components, ostensibly to improve the user experience. The handling of these come at some cost, and various components are faced with decisions about whether or not to permit non-conforming messages to continue toward their destinations unaltered, adjust them to conform (possibly at the cost of losing some of the original message), or outright rejecting them. This document includes a collection of the best advice available regarding a variety of common malformed mail situations, to be used as implementation guidance. It must be emphasized, however, that the intent of this document is not to standardize malformations or otherwise encourage their proliferation. The messages are manifestly malformed, and the code and culture that generates them needs to be fixed. Nevertheless, many malformed messages from otherwise legitimate senders are in circulation and will be for some time, and, unfortunately, commercial reality shows that we cannot simply reject or discard them. Accordingly, this document presents recommendations for dealing with them in ways that seem to do the least additional harm until the infrastructure is tightened up to match the standards.
