Open WebMail is a webmail system based on the Neomail version 1.14 from Ernie Miller. Open WebMail is designed to manage very large mail folder files in a memory efficient way. It also provides a range of features to help users migrate smoothly from Microsoft Outlook to Open WebMail.
Open WebMail project is an open source effort made possible thanks to volunteer contributions by hundreds of developers around the world. But volunteers can't do everything: it takes money to host our server and coordinate the work done by volunteer contributors.
