This software block SMTP sessions used by e-mail worms and
viruses on the NA(P)T router. It depends on netfilter
framework of Linux, or ipfw on FreeBSD.
It acts like proxy, intercepting outgoing SMTP connections
and scanning session data on-the-fly. When messages is
infected, the SMTP session is terminated. It's to be used
(mostly) by ISPs, so they can eliminate infected hosts from
their net work, and (preferably) educate their users.

sender is unknown, ASK sends a "confirmation message" back, informing
the sender that the original message has been queued, pending confirmation.
When the sender confirms (a simple reply), ASK delivers the original

sender will be immediately delivered. It is also possible to ignore
messages based on specific criteria, like sender's email, subject and so on.

blacklists function, where fallable humans (many with political agendas) must
process thousands of reports and make decisions - many times after the fact.
The RABL is fully reactive to new threats and can block addresses within
seconds of widespread infection - good to know in this world of drone PCs

cleared a minimum duration (an hour by default) without any additional

Anti-Spam SMTP Proxy is a spam filter that sits on port 25 in front of your
regular SMTP server (sendmail, postfix, qmail, etc).
ASSP performs a number of configurable spam checks, and on detecting a spam
message, provides an immediate 5xx SMTP error code back to the client.
Non-spam messages are passed to your regular SMTP server for further
processing and delivery.
ASSP offers:
- a whitelist of known good senders
- Bayesian checks on message headers and contents
- recipient address validation using LDAP and RFC822 conformance
- relay denial
- HELO checking
- SPF (Sender Policy Framework) checking
- DNSBL (DNS Block List) checking using many DNSBL services
- Virus detection

The milter recives messages from sendmail, and saves them as a file in
a directory. The directory name and the file name are the "$i" (queue
identifier) from Sendmail, making it easier to identify them. Once the
entire message has been received, the milter runs "ripmime" on the file
to extract any attachments. If rupmime returns without an error then it
will run "uvscan" on the diretory to scan all the files in it. If uvscan
returns an error, then the milter will look for viruses output from
uvscan, and reject the message reporting which viruses were found. If
viruses were found then the entire directory is moved to quarantine,
otherwise it is deleted.
The milter also does extention checks. Certain extentions are blocked
completely. In specific, extenions of .scr, .vbs, .pif, and .com are
blocked.
