So far we have...
The program will manage messages and mail folders pretty well now.
Sending mail via SMTP and receiving via POP3 is working. POP3 passwords are not handled securely in that the password is stored in plain text form in the configuration file.
Adora now supports multiple POP mailbox configurations, and further improvements will be made with this soon. A nice POP configuration interface is now provided.
Replying and Forwarding messages works now.
The Nicknames implementation is a pure ripoff on Eudora Light. In fact, it actually uses the same file format as Eudora. This will probably be completely changed, in order to have compatibility with MH and a better implementation for groups. Maybe I'll use the current nickname code to build a nickname importer for Eudora Light nicknames.
MIME is partially implemented. If the software detects a multipart document it will let you save text or base64 documents from it.
