What happened?

emails received from @outlook.com are not getting into the mailbox of the recipient.

Possibly because of this ?

I'm getting emails from a lot of different mail provider without issue.

How can we reproduce the problem?

1 - create an account on outlook.live.com
2 - send an email from the @outlook.com to an email of the stalwart server
3 - observe that the email is not received.

Version

v0.9.x

What database are you using?

After checking my dns zone and comparing manage/directory/domains/example.net/view, I saw missing tlsa fields. Setting them correctly fixed the issue.

Try setting the log level to trace and check your logs again.

Here's the relevant log output.
It seems the tls version used by the sender is incompatible with the one stalwart uses ?

This is an error coming from the TLS library used by Stalwart and there is not much we can do to fix it. Have you disabled any ciphersuites? Are you using a TLS certificate issued by Let's Encrypt? Are you using a reverse proxy?

You could also try sending a test email from that Outlook address to [email protected] to see if our server has the same issue.

Have you disabled any ciphersuites ?

no.

Are you using a TLS certificate issued by Let's Encrypt?

yes

Are you using a reverse proxy?

Only for the Web UI. smtp/imap ports are opened and used directly.

I have sent an email to [email protected] at 17:48:50 UTC with the subject: "test for discussion 750".

After some days, outlook will send back an email to notify the sender that the email sent could not be delivered.
Here's the content.

Can you provide more info on this ?

It worked:

Edit: try without the reverse proxy in case it's breaking the TLS handshake somehow.

so it must be something configured differently on my end then. I will try to find how to allow invalid DANE since it seems to be the issue here.

try without the reverse proxy in case it's breaking the TLS handshake somehow.

I'm not using a reverse proxy for imap/smtp, only for http.

After checking my dns zone and comparing manage/directory/domains/example.net/view, I saw missing tlsa fields. Setting them correctly fixed the issue.
