When I refer to "email services" I mean SMTP, POP, IMAP, web mail interfaces, and the back-end administrative tools. Do many/most ISPs use big, expensive enterprise tools for this? Piece their own systems together using various commerical/free tools for the different parts? Or do they roll their own almost top to bottom? I have experience doing email for small and medium corporate sites (in the 100's of internal users), but the particular project I am working on is for customers, not internal users, and could quickly balloon from the few dozen on the current demonstration system to a few thousand. Any firsthand info or pointers to more information would be greatly appreciated. -- Crist J.
