Hi,
maybe a silly question, but I have not read something about IMAP servers. So, are all IMAP servers in that way the same, that they have all the same API. Example: I think, we have no Autoresponder implemented in RoundCube (if so, don't care - it would be a simple nice training to get a programming start). If I now like to make one, not writing an autoresponder itself, activating the feature on the IMAP server, is where an API saying me, you have to send this command to the specified server to do so and _all_ IMAP servers will understand it, or for example, the All-Inkl.com IMAP server and the web.de/freemail.de IMAP server handle it in different ways, so that I need to question every provider, how they have set up their server for that task. And please tell me, that this is normalized for all IMAP talking servers...
