DONE Honeypot (Spamtrap)

| Last activity: more than 10 years ago
Blacklist the sender IP address of those writing to specific local email addresses, e.g. addresses published on the company web site specifically as honeypot (spamtrap) addresses. This feature would be based on the assumption that whoever sends email to the honeypot address(es) must be a wrongdoer, because the honeypot address may be collected only by robots scanning the internet (and the web, specifically) for email addresses, which is a typical spammer behavior.

DONE Directory Harvest Attack (DHA) Protection

| Last activity: more than 10 years ago
Add a new test to ORF that would temporarily reject all delivery attempts if the sending IP address is sending to more than "X" (user-configurable) non-existent recipients within in a specified period of time. This would provide some protection against poorly distributed or non-distributed Directory Harvest Attacks.

DONE Update SPF Test To The Latest RFC

| Last activity: 5 years ago
ORF implements an earlier (draft) version of the SPF specification instead of the final version RFC 4408. Update the SPF implementation in ORF to RFC 4408.

SCL Scoring

| Last activity: 4 years ago
