I'm maintaining the Win32 build of the "shared" development branch. Another participant maintains the Linux build system and converted it to use the auto tools. The main drawback to Mulberry is that it doesn't display images, and its HTML rendering is primitive. But if you're like me and deal primarily in text, and want to only open images and attachments explicitly (good way to avoid infections), Mulberry works great. It's particulary wonderful if you have a huge hierarchy of folders. I've got literally hundreds of mailing list folders, with procmailrc feeding mail into each, and Mulberry is great for detecting new mail in all of them efficiently. Mulberry has a great Reply selection dialog. When you reply to an email, a dialog optionally appears letting you easily select which correspondents will go in the To/Cc/Bcc fields, and whether the reply is really a reply (with References header) or a New Message. Again, very useful for dealing with mailing lists when you want to start a new thread. You can configure multiple "identities" representing what will populate the >From and Reply-to fields and what outbound servers will be used. An identity can inherit from another identity, changing only what's unique, so you can create a default identity and the others can have minimal setup. Each mail folder can have an identity associated with it, and this is inherited by child folders or can be overridden. Folders can also have unique notification sounds. I don't use Mulberry's filtering system because I use procmail on the server for that, but I know a system is there should you need that.
