Are you on DigitalOcean? They are known to block outbound mail ports on new servers, particularly on new accounts. Reach out to them to get it unblocked if so, but use 587 if possible! 465 was revoked by the IETF years ago.

Not DigitalOcean. I use other Ubuntu VPS and Yandex as smtp server. Curl fails on 25, 2525 and 587 ports, but works on 465

587!

Utilizziamo diversi siti Discourse con Yandex. E ovunque con la porta 587 funziona perfettamente. La porta 465 non funzionava inizialmente.
