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. Written in PHP (7.3+) the entire system including web management and css is currently less than 2MB. Melee requires a single MariaDB/MySQL table for member management and 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.
Created by Mike Harrison of GeekLabs.com for Chugalug, who struggled to maintain it as a sharable project at GitHub. Now a Microslop property. If you want the code, reach out and I'll email you the current version.
The struggle comes from Mike's bad habits of editing code in production and hard coding things that should be config variables..
