Hi, I am coming back to this because we woudl still really appreciate this feature. Our use case is as with tamayers that different groups of employees use different systems (partly for legacy reasons, partly because they wish to do so). This means we have a group on google workspace, we have a group on microsoft exchange, and I have a group on cloudron. Now our workaround is quite messy and simply adding the option to force cloudron to do an external MX lookup would solve this problem: The problem is that if I then send a mail from an email-adress hosted at the cloudron instance to email adress hosted on google but on the same domain it runs into delivery problems. At the moment, our workaround is to have all of these account also existing on cloudon and then have them forward the emails to a mailbox on a different domain, which is then forwarding the emails back to the Google or the MS Exchange Server. So quite messy.
Hence we would really, really appreciate if you could implement this feature soon.
Do you think there is any chance you can implement this soon?
