Cloudron Forum

So I have played about for days, I did this because when trying EmClient, it said there was an SSL issue, and it was not the only place I saw an SSL error, and when clicking reissue, I saw there were lots of issues with trying to generate a SSL for imap.domain.name I changed the mail server URL from imap.domain.name to my.domain.name and then checked DNS. I noticed the DNS had not been updated, did it manually. I checked the logs as the process was being done, it stated that the DNS record had been updated, but it had not. Since changing my mail server address to the same URL as my cloudron server, the connection seems to be more stable, with faster responses and no SSL errors. Outlook it still not working and seems to find the old URL where as all other apps are seeing the new URL and still loading the imap.domain.name, we have given up on this issue. What is the point in being able to change the domain name and subdomain of the mail server when it don't seem to be liked by mail clients.

@czeimke can you update to 8.2.3 ? Is this still a problem?

Thank you that made me understand the differences quite well. Sadly it seems like the issue is not resolved yet though. The Outlook client seems to stay slow. It was just shortly working a bit better it seems. What I don't understand is the following though: Only the modern Mac Outlook is slow/buggy. If I switch to legacy outlook there are no Problems. Thunderbird is having no Problems as well, same with other clients. I found out though that when I enable Offline Mode in the modern Outlook Mac client, then the search is not slow anymore. Still there is the problem that Attachments are buggy and when you try to open them Outlook says that they have to be redownloaded to open them (which does not work). The modern Outlook for Mac does work with other IMAP clients though. So It's not Purely an Outlook problem and not Purely a Cloudron Mail problem. There just seems to be a problem in the communication between them. I just seem to no be able to debug it. Does anyone have an idea what it could be?
