In his development on a Windows environment, Daniel Cousineau has come across a hurdle - sending emails from his local machine from his PHP scripts. Thankfully he's found a solution and has shared it in a new blog post.
Previously it was a simple trek to a website to download a Windows build of sendmail.exe, but for some reason I cannot get access to it, so I have to go another route. Enter hMailServer, a free, full-featured SMTP/POP/IMAP server for Windows with a pretty, shiny GUI configuration interface. All I really want to do is setup SMTP for localhost only but one could easily use hMailServer as a production mail server.
He includes the details (along with some screenshots) to get the hMainServer software up and running. Thanks to the simple GUI the tool offers you can be up and working in a few clicks - oh, and a change to your php.ini file.
