Buongiorno, da diverse settimane ogni volta che mando una mail dal mio indirizzo [email protected] (appoggiato a Thunderbird) ad un indirizzo gmail, mi torna indietro la mail con il seguente errore:


This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: 

 [email protected]
   host gmail-smtp-in.l.google.com [108.177.127.27]
   SMTP error from remote mail server after end of data:
   550-5.7.26 This mail is unauthenticated, which poses a security risk to the
   550-5.7.26 sender and Gmail users, and has been blocked. The sender must
   550-5.7.26 authenticate with at least one of SPF or DKIM. For this message,
   550-5.7.26 DKIM checks did not pass and SPF check for [paolazziambiente.com]
   550-5.7.26 did not pass with ip: [185.81.2.212]. The sender should visit
   550-5.7.26  https://support.google.com/mail/answer/81126#authentication for
   550 5.7.26 instructions on setting up authentication. qm13-20020a170907674d00b009334769e7ebsi105646ejc.790 - gsmtp

Questa cosa mi succede solo con indirizzi di invio aventi dominio gmail. Come posso fare?

Grazie

Sembrerebbe che Gmail consideri il tuo server di posta NON sicuro, probabilmente perché non implementa SPF or DKIM o non supera i relativi controlli.

Non è qualcosa che puoi risolvere da Thunderbird. Devi segnalare il problema a chi ospita la tua casella di posta ed eventualmente anche a Google.
