This is a question I've tried to answer for a long time now. I'm currently working on a personal project on a windows XP machine and it's come to the point where I need to send emails to test some functionality.
I'm looking for an application that I can setup that mimics an SMTP server or actually IS an SMTP server that when PHP runs the
mail() command, this application will catch said email and store it in a way that is easily retrievable by me.
Another post on here on SF mentioned an application called Neptune, however website hosting that does not exist anymore.
