It is fast and does its job well. **What do you dislike about OpenSign?** We use the self hosted option through docker, as emails in opensign are sent by default using the user email address, yet the smtp setup uses only a global authentication, we have issues with emails due to incompatibility with username and and the smtp authentication.
