The default configuration provides a spam detection system, monitoring, reporting and backup mechanisms.[6] It can also set up and automatically renew a Let's Encrypt certificate, as well as configuring the detailed DNS configurations needed to ensure that a mail server's IP address is trusted by other servers, and less likely to be blacklisted.[6][7] Its support for IMAP/SMTP facilitates synchronizing across devices.[7]
First developed in 2013 by Tauberer, the tool is written in Python. The project supports Ubuntu LTS.[8][9]
It has been recommended by the notable Hackaday and MakeTechEasier.[10][11]
