С 00:00 первого января, до 16:30 четвертого января, в заголовках писем, пришедших в Яндекс.Почту, будь то @ yandex.ru или почта для домена, вместо месяца получения письма попадали куски кода на сях.
Пример заголовка:

С товарищем akke, который изначально и обнаружил столь странную штуку, мы собрали все кусочки, которые попадались, собрав заголовки из 400 писем.
Данные в заголовках доступны по прежнему, поэтому можно посмотреть их на любом почтовом ящике Яндекса.
Ну а теперь то, ради чего я это пишу:
Что это было, и как вообще могли попасть куски компилируемого кода в заголовки письма?
