linux default iconspamdyke Publisher's description

spamdyke is a filter for monitoring and intercepting SMTP connections between a remote host and a qmail server.

spamdyke is a filter for monitoring and intercepting SMTP connections between a remote host and a qmail server. Spam is blocked while the remote server (spammer) is still connected; no additional processing or storage is needed.

spamdyke boasts a large number of filters for blocking mail from remote servers. Every filter is individually configurable.

spamdyke's reverse DNS filters can:
* Require reverse DNS names.
* Require reverse DNS names to resolve with IP addresses.
* Require reverse DNS names to be real, not dynamically assigned.
* Require the sender's domain name to have a valid mail exchanger (MX).

spamdyke's blacklist and whitelist filters can:
* Search local IP and reverse DNS blacklist/whitelist files.
* Search DNS realtime blacklists/whitelists (DNS RBLs).
* Search DNS righthand-side blacklists/whitelists (DNS RHSBLs).
* Search sender and recipient blacklist/whitelist files.

spamdyke's graylist(/greylist) filters can:
* Graylist specific recipient domains (activated per domain).
* Graylist connections from specific IP addresses or reverse DNS domains.
* Enforce minimum and maximum ages for graylist entries.
* Skip graylisting for specific domains, IP addresses or reverse DNS domains.

spamdyke's other filters can:
* Stop earlytalkers (remote servers that send data before the SMTP greeting banner is sent).
* Limit the maximum number of recipients per message.
* Enforce idle timeouts and absolute timeouts.
* Prevent unauthorized relaying.
* Stop spam that appears to come from the recipient's address.
