Yandex Kurumsal Mail, İmzaya resim ekleyince mail gitmiyor

Merhaba,

Yandex kurumsal mailden bir yüzüm gülmedi,

İmzaya resim eklenince mail direk sunucudan red yiyip geri dönüyor.
Gmaile gönderirken oluyor bu sorun, normal başka alan adlı birisine gönderiliyor.
Gmailler de problem oluyor.

Aşağıda ki hatayı veriyor, yardımlarınızı bekliyorum.

Resmi import değilde embed şeklinde eklemeyi deneyin. Yani resim ekte gözükmeyecek fakat harici siteden açılacak.
