Issues sending email to recipients - however mailbox is connected and working in some cases

[madsamjp]

When I create a document, it fails to send to recipients with the error 550 Request failed; Mailbox unavailable (see below log)

If I self sign the document for both recipients, it sends the the signed document to both recipients just fine. After signing, I can also email myself a copy and that works just fine too.

So, the fact the email is sending just fine when I self-sign compared to trying to send out the unsigned document to the recipients suggests this is an issue with docuseal and not my mailbox.

EDIT - just to note I've tried this multiple times and get the same behaviour suggesting this is not a temporary network issue.

Here are the logs for the failed example and the successful example:
