New features and enhancements
- Support for non-MIME parts (no "Content-Type" header), with uuencode'd attachments
- Cache 'maildir' data (folder and message index)
- SMTP Service Extension for Message Size Declaration (see RFC-1870)
- PGP-MIME (RFC-3156), S/MIME
- Implement message search for stores that support it (IMAP, maildir?)
- Check IMAP4/IMAP4rev1 capability in IMAP connection code
- Allow to move messages between folders (
net::folder::moveMessage()) - IMAP, POP3: reissue CAPA command after authentication (as with SMTP)
- Support for objects referenced by an URL in MHTML aggregate documents (see RFC-2557)
- 'mailbox' storage support
- Error handling for Windows sockets (use socket_exception(), like in POSIX sockets)
- Implement logging facility for all messaging services
- Implement the following RFCs:
Refactoring
- Move POP3 connection code into a new POP3Connection class
- Move SMTP connection code into a new SMTPConnection class
- Change data type for socket::sendRaw() from 'char' to 'byte_t'
- Check for abusive use of C++ exceptions. Exceptions should only be used for error handling scenario, not for normal flow (eg. a "field not found" should not throw an exception)
Quality & Testing
- Unit tests for IMAP parser
- Test IPv6 support
