We have a person using Thunderbird whose mails carry the following header: From: =?UTF-8?B?IlBhd2XFgiBIYWpkYW4sIEpyLiI=?= <phajdan.jr@gentoo.org> If you decode the base64, you'd see (with literal double quotes): "Paweł Hajdan, Jr." In the message view, the header is displayed as: From: "Paweł Hajdan, Jr." <phajdan.jr@gentoo.org> If I click the address, everything works fine. However, if I try to reply to him, claws-mail splits the address into two parts: To: ""Paweł Hajdan To: Jr."" <phajdan.jr@gentoo.org> which obviously results in broken mail that gets queued and refused by server afterwards.
