I am using eMail client and use the email signature feature. When I create it (in eM Client) I insert a picture in the signature as well.
This seems to work fine for a while but then at some random point in time the picture in the email signature seems to disappear and when I then try and send an email a get the below error message.
The picture in my signature then look as follows and I first need to delete it from my signature before I am able to send the email.
Why does this happen and how can I fix this?
