Postie!
The built-in WordPress PHP script to grab e-mails and generate blog posts from them wasn’t particularly good, so I’m now using Postie (http://wordpress.org/extend/plugins/postie/), which seems to at least offer more features, though this post is really an experiment to see how well it works.
I keep having issues with the built-in WordPress installer, so I think I’m just going to use the command line and grab everything via wget.
Edit: This worked perfectly, and I definitely like Postie more than the built-in wp-mail.php method. Definite plus: being able to add tags to the post by e-mail, among other things. I’m going to have fun with this. Also, Postie supports POP3 with SSL without my ssl://server hack. I think it ends up working the same way, but the additional layer of abstraction makes it dead simple for a first-time user.
