Email is not configured properly

@roru2k20 Probably just wait. If this is the first time you've set the DNS records, it can take up to 24hrs for it to be propogated. Which registrar is this on? On Namesilo it's taken literally under a minute for me (for the same kind of records), while with others, like dynadot it has taken over 24hrs.

@scooke thanks, but my configuration is about 1 week old.
I thought it is a problem that cloudron runs on a Subdomain of a Subdomain

[scooke]

@roru2k20 I'm curious... this works? Because https://docs.cloudron.io/installation/ supposes the Dashboard is on a subdomain only, not a sub-subdomain. You can install apps, and they work? Like, app1.secondlevel.com, and app2.secondlevel.com. I mean, Mailgun is aware that emails on subdomains are possible, so, it should work.

TBH, I'm not sure how this would affect the email domain. Since the Email Dashboard is telling you what you need to enter, and you've entered it, and it's been a week, something's gone wonky.

Is the failure for email for anything at @thirdlevel.secondlevel.com, or @secondlevel.com, or specific apps, like user@app1.secondlevel.com?

DNS just seems like a wizardy thing to manage well. I think the easiest thing would be to follow the recommended/assumed install, using just a subdomain.

It is possible that you need to make an A record specifically for those 2 layer domains, rather than letting the * handle everything. So rather than just @ and * in your A records, you may need to specify A thirdlevel.secondlevel.com IP. Let us know what the solution is.

@roru2k20 The UI should say what is the expected value and what is the current value. Can you see anything obvious?

You can also check if the DNS has propagated with the host tool like this:

host -t TXT cloudron._domainkey.thirdlevel.secondlevel.de and host -t TXT thirdlevel.secondlevel.de. Do they match what Cloudron is expecting?

Hello @scooke!

Yes that works! I run on this Gitea and for my own app packaging code-server (VSCode) really well, but not email.

Now he is showing me that only the SPF is wrong.

@roru2k20 Note that for SPF you have to add a TXT record. In some DNS providers, there is a so called "SPF" record type and that is not the correct type to use.

@girish

I know what you mean, but I have no other choice. This is a combined entry SPF (TXT)

[girish]

@roru2k20 I see. Just to double check, the above DNS records are for the thirdlevel is it? If not, they should be added as "thirdlevel" and not just "@" (for the SPF record at the bottom)

[roru2k20]

@girish some entries are for the second level domain and some for third level.

SLD = Second Level Domain
TLD = Third Level Domain

MX 10 -> SLD
MX 20 -> TLD
Last @ -> SPF -> a: SLD include: my.devenv.SLD.de
my.devenv.SLD.DE
git.devenv.SLD.DE
code.devenv.SLD.DE
.... and so on.

Problem solved by install all three instances into one and bought a license from cloudron. Now it works
