иногда не импортируются в ютрак письма с крупными вложениями(> 10мб)

настроил ютрак как сервисдеск

часть писем(большая) проходит нормально,

часть подвешивается в подпапке для импорта и не появляется в ютреке и не стирается

youtrack 2017.04 на нашем сервере

по подобной теме в интернете нашел лишь упоминания о том что такое поведение может быть если отсутствуют заголовки с мессадж id

но это похоже не мой случай(ниже заголовки приведу), есть ли ограничения на размер входящих вложений?

===

привожу часть письма(заголовки)
