I have this issue also, but my set-up involves having my submission server send all emails to an internal mail relay, which then sends to the destination SMTP server. I'm using "dane-only" for the connection from the submission server to the mail relay, meaning that it is used for all external outgoing mail. So I'm seeing the same same behaviour as described above, but the deferred message is slightly different:
to=<x...@gmail.com>, relay=none, delay=0.13, delays=0.1/0.02/0.01/0, dsn=4.7.5, status=deferred (no TLSA records found) I can only assume that the different message is due to a difference such as not using MX look-up to send to the mail relay? But I thought I'd mention it in case it is relevant? And just to confirm, yes this problem started after I performed the dist-upgrade to Focal Fossa. FYI As a workaround I've changed to using "encrypt" instead of "dane-only". I'm happy to provide more detailed information (e.g. configuration files) if it would help?
