Hi!
I'm using webklex/php-imap 2.2.0.
Protocol: imap.
I want to get attachments from letters, .zip files are being saved properly (e.g. Astronomia0091023-2020-11-05.zip),
but one letter has .xlsx file attached with name "Прокрастинация и другие методы избежать работу 2020-11-02.xlsx" and its saved like "undefined" without any extension (not even undefined.xslx).
I saw the issue #37, but it's not solving this problem. Can you help?
