As defined: Melee - a confused mass of people. "the melee of people that was always thronging the streets"
Mailing Engine List Engine: A very small mailing list manager writen from scratch for small to moderate sized mailing lists. 2 to 1000+ people. A sharable version will be posted to GitHub soon. Written in PHP (7.3+) the entire system including web management and css is currently less than 2MB. It currently requires a single MariaDB/MySQL table for member management, a working SMTP and IMAP server. Unlike legacy mailing list managers and mailing engines, Melee receives from an standard IMAP account, and emails via a standard SMTP server. Configuration is via editing a single config file.
Currently, all administrative functions are CLI and SQL, but a seperate admin web interface is in the works.
