We are pleased to announce that eMPF is available for download
at our website.

We'd love to get some feedback on this package. Currently it has
only been tested with vpopmail-enabled systems, however, it shouldn't
be too difficult for some to configure the package to work with any
other qmail system. The following is from the eMPF webpage at

eMPF follows a set of administrator-defined rules describing who can
message whom. With this, administrators can segregate various parts of
their organizations email activities, as well as provide a variety of
security-enhancing services. Because of this, eMPF can help to support
HIPPA and Sarbanes-Oxley compliance.

During an SMTP session, when a sender identifies themselves, either via
SMTP_AUTH, or via the message envelope, as well as a recipient, eMPF
loads applicable message policies to determine if the sender is allowed
to message the sender, and if the recipient is allowed to receive mail
from the sender.

Because mail from outside your mail server cannot be authenticated, the
policy framework cannot be entirely sure about the identities of senders
messaging local users. However, if SMTP authentication is required by
local users, eMPF can prevent remote users from masquerading as local
users to bypass policies.
