Additional info

All other email clients seem to resolve fine and I've verified with a few tools that the mx is configured correctly. When manually configured it can correctly access mail boxes.

What are the expected configuration parameters? You could look them up in the provider docs or try another email client like Thunderbird.

I've screenshotted the expected auto configured parameters below, so far all the other email clients we've used resolve these correctly:

Thanks! We should be able to debug this

Hey there! Could you please share the domain with us? If you'd prefer not to post it here, feel free to email me at danielk@nextcloud.com.

Based on the information at https://www.spaceship.com/roadmap/?feature=email-auto-discovery-auto-configuration-for-spacemail, it seems that auto discovery isn't available, so it's likely that our guessing didn't find the right mx.

Heyo, I sent you an email with the end domain, I can also provide a burner email account for the domain if that would help in resolving the issue!

[kesselb]

Thank you,

I'm unsure if we can do something here. The auto discovery looks at the ispdb and the mx records.

IspDb:

https://github.com/nextcloud/mail/blob/912779f0c3640f822332be2dd829103dc3dc57f3/lib/Service/AutoConfig/IspDb.php#L35-L39

=> Your domain does not provide an xml document with the conncecitiy parameters and is also not enlisted in mozilla's list.

MX:

=> The mx records for your domain resolve to mx1.spacemail.com and mx2.spacemail.com.

Thunderbird was also not able to find the right configuration for your domain. Which email client was able to look up the settings automatically?

Hi there! It looks like this issue hasn’t seen much activity for a while and might need a bit more information to move forward. If we don’t hear back soon, we may close it to keep things organized. Thanks again for your contributions – we really appreciate it!
