If I interpret the homepage correctly clients/servers without extra COI enhancements will just receive the messages as emails. Not ideal, but in any client with threading (gmail, apple), it would work decently i guess.
- tom_mellior 8y agoAccording to the spec (https://confluence-public.open-xchange.com/display/CoiW/COI+Client+Specification+v1.0 https://confluence-public.open-xchange.com/display/CoiW/COI+...) clients are expected to ask the IMAP server using a CAPABILITY command whether it supports COI extensions. Whether or not the server does support COI, messages are indeed standard mails with an extra Chat-Version: header and the requirement that Message-Ids start with "coi$". So an existing server need not do anything to support COI clients. But a malicious server could easily decide to reject them, or to filter out COI-specific stuff from messages. I don't think it's likely, but it sometimes big corporations and governments get paranoid about weird things ("network load!!1!") and take technical measures to block them.
- m0dest 8y agoI wouldn't be surprised if COI encounters issues with automated abuse detection and spam filters in those servers. When you're in an active conversation, the client is rapidly sending 1-line emails with strange headers.
