The DNetMail project aims to develop a morden, extensible, full featured Internet
mail (SMTP/POP3/IMAP) infrastructure capable of handling millions of messages
per day with full support for real-time e-mail analyzes.
Features
- Secure
Built from the ground up with security as a top priority, the core system only
manages the protocol state machine and the hook dispatching machinery. Everything
else is taken care by the hooks implemented using high-level safe languages.
The core works as a powerful "virtual machine" sandboxing unsafe, complex and
error-prone code. This approach improves security without losing functionality.
- Customizable
Each DNetMail component has built-in support for Perl, Python or Ruby hooks for
authentication and system configuration, the hooks also control message archiving,
retrieval and filtering. It allows you to supply event hooks (script functions)
that are invoked on significant steps used in manipulating, sending or receiving
messages. All high-level functions and features are implemented using the hooks
for safeness, extensibility or redefinition.
- Extensible
Using the extensible library of functions available in Perl, Python or Ruby
one can easily set up authentication against a database, LDAP directory or
through PAM. There are also a number of hooks where real-time analysis of
messages can be placed for spam and virus detection. You can also redefine
the behavior of things like message persistence, quotas, error messages,
header rewriting, you name it.
- Efficient
The core system design maximizes concurrency and optimize performance by
using an multi-processing architecture where a dynamic pool of small
processes are responsible for managing client sessions and multiple hook
interaction. One blocked hook does not stop the entire system.
Status
The project is in the early phases of development and not expected to be
finished soon, but your input is important. You are invited to join our
mailing list and discuss requests or comments!
