Hi Alaxander,
No, I don't use my mail server to post on this list. I use my ISP's.

Yes, reviewing your mail headers confirm this. So I suspect the second DSN came out a context where you still had the misconfiguration with localhost.localdomain as hostname and not already relaying through your ISP.
"(reason: 521-EHLO/HELO from sender 71.31.91.127 does not map to localhost.localdomain in DNS)"
sounds obvious for me.
All should be fine now.
Cheers
