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 includes SSL and IPv6 support. It is a single
|
|
script with a web-based configuration tool.
|
|
|
|
ASSP offers:
|
|
- a whitelist of known good senders
|
|

|
|
- recipient address validation using LDAP and RFC822 conformance
