Hello, since one week I receive error messages from my email recipients, and I cannot deliver my email messages. The reason seems to be due to the fact that Thunderbird adds bare line feed characters to the emails. The error message is the following: "Your message contains invalid characters (bare line feed characters) which the email servers at libero.it don't support. ... Bare line feeds unsupported

How to Fix It It appears that your email program added invalid characters (bare line feed characters) into your message when you sent it. Try using a different email program to send your message. If the problem continues send this non-delivery report (NDR) message to your email admin for assistance.


..." I recently updated my TB version to 102.1.2, but this did not help. Looking on the web, this error message is not new, but recently happened to other users (https://stardot.org.uk/forums/viewtopic.php?p=366951), without an evident solution. Can someone help me to solve this? Thanks so much

Come soluzione tampone prova a comporre i messaggi come testo semplice: Tieni premuto Maiusc e poi fai click su Scrivi (o su Rispondi)

Dopodiché però, se il problema riguarda solo i destinatari su libero, mi sa che non c'è molto da fare.

grazie. quello che ho inviato è solo un esempio, in realtà riguarda i destinatari anche exchange o altro, e in generale per risolvere devo reinviare la mail, a quel punto da webmail o da outlook (che non sopporto tanto..). e dalla prova che ho appena fatto anche inviando i messaggi come testo semplice il problema non si risolve.. grazie comunque
