one of our clients receives encrypted emails with a single small text attachment, send by
some specialized appliance.
The problem is, that after decryption, the attachment seems to have disappeared. Since the
attachment only contains one or two lines of text, it isn't helpful to compare the
size of the email before and after decryption.
Which loggers do I have to switch to debug to see, what happens to the attachment?
Since there is a large number of other emails with attachments, which are decrypted
correctly, I doubt that it is a Djigzo problem. But at least we have to proof it.
