Sure. Your connection test says that you can use port 465, but you can not use port 587. That’s not a problem.
5.1.1 recipient rejected
Postman said to the server “I want to email this guy” and the server said “no”. Maybe the email was invalid, maybe their mailbox was full, maybe the account didn’t exist. There are lots of reasons why the recipient would be rejected.
There’s nothing you can do on your end, the problem is with the recipient’s account. If you think the email address was valid, then checking the transcript for the failed message might provide more clues.
I sent a message as a notification of a new post to about 20 address. If it does not work now, which mailbox is full? I don’t obtain failed message and the test mail arrives regularly.
I try with port 587.
Go the logs in Tools -> Email Log, find the email that failed to send and paste the Transcript here.

Your SMTP server “paganini32” is rejecting address “[email protected]”. I do not know why, you’ll have to ask the administrator. Send them a copy of the transcript.
I deleted “[email protected]” from subscriber list and the notification was delivered.
I think the problem is solved.
Thank you very much for your time.

@claudio-pellizzari, I forgot to mention that you should change your password ASAP.
In the future don’t post email session transcripts online. They contain your account username and password, in encoded form.
