After upgrading to 5.6, when we try to respond to letters with embedded logos, we get errors.

Error:

I've faced the same issue today, but only when forwarding an email. Replying didn't cause any problems.

The cause was two attachments with the same file name. By removing one of the files, the forwarding was ok.

Espo version is 7.0.8
