hi
i'm playing with a nas i've installed debian stable on, and i used to
have some scripts with mailx work to send me messages through external
providers/servers/etc till i upgraded debian: now i can't send mails
through mailx but i can through telnet and swaks: here are mailx and
swaks logs, please treat me as a true noob
ok.
this contains the message, that one ...

As simple as it can be, your "mailx" approach needs SMTP-AUTH support or
your mailserver needs to allow your actual ip as a relayhost without
smtp-auth. If you have trouble adding smtp-auth to mailx, you could
revert to an old form of authentication: pop-before-smtp, but honestly,
use a better mailclient if mailx can't support smtp-auth.
best regards,
