Is there a way to prevent the quotes from being added or displayed? Thank you. August 17, 2026 at 9:11 am #358223 MichaelKeymaster Hello, which email client are you seeing that with? Michael August 17, 2026 at 10:56 am #358234 JanParticipant I’n using Thunderbird. Of course, i dont see those single quotes in other E-Mails. August 18, 2026 at 8:59 am #358247 MichaelKeymaster Hi, can you send a test email to michael@qdpnews.it (it’s a test address of mine)? Thanks August 18, 2026 at 9:02 am #358248 MichaelKeymaster Also, I know that Outlook wraps sender name around single quotes when the contact is not in the address book, not sure if Thunderbird does something similar.
