Problem with MDaemon IMAP

#1

I have MDaemon POP3/IMAP/SMTP server which is working flawless with Outlook 2010-2016. Now I’m trying to make it work with Delta.Chat with no luck. SMTP works fine and messages go out. But IMAP do nothing.

MDaemon log:

Delta Chat log says all the time the same:
05-14 20:33:22.017 9860 9883 I DeltaChat: 0 mails read from “DeltaChat”.
05-14 20:33:22.018 9860 9882 I DeltaChat: 0 mails read from “INBOX”.

Whats the problem?

Which version of Delta chat are you using? on which platform? which version of the core does it use(that can be found as first thing in the logs or on an about page)?
