PostFend Reputation Listing & Delisting Policy
1. Purpose
To protect our customers, PostFend keeps reputation data about sending infrastructure: IP addresses, domains, URLs and file hashes. A listing affects only how PostFend treats mail.
We do not publish a public blocklist.
2. Listing criteria
We list a source only on objective, recorded technical evidence, such as:
| Code | Criterion |
|---|---|
| R1 | Mail hit our spam-trap addresses 10 or more times in 7 days |
| R2 | Confirmed malware or phishing content or URLs |
| R3 | SPF/DKIM/DMARC failures combined with another abuse signal |
| R4 | Open relay or compromised host, verified by test |
| R5 | 5 or more distinct customer reports in 7 days |
| R6 | Listing on a licensed third-party feed (the feed is named in the record) |
Each listing records the criterion code, an evidence reference, the date and time, and the expiry date.
3. What a listing means
A listing is a factual, technical statement that traffic from a source met a criterion at a stated time. It is not an accusation that any person or business acted unlawfully or dishonestly.
Notices state only the criterion and the dates. For example: "Listed under R1: 14 spam-trap hits between 2026-11-01 and 2026-11-03." We never describe senders as "spammers", "fraudsters" or similar.
4. Expiry
Listings expire automatically after 30 days unless new evidence is recorded.
5. Delisting is free
- Submit a request at https://postfend.com/delist or to [email protected]. No account is needed.
- We never charge for delisting, and we never sell priority delisting.
- Please provide the IP address or domain, a contact, and any steps you have taken to fix the problem.
- We acknowledge requests within 1 business day and decide within 3 business days.
- If the criterion no longer applies, or the listing was mistaken, we remove it and record why.
- If we decline, we explain which criterion still applies and what would resolve it.
- You may ask for a second review by a different staff member.
6. Third-party feeds
If a listing comes from a third-party feed, we name the feed so that you can use its delisting process. We may override the listing locally once the issue is fixed.
7. Records
Listing and delisting records are kept for 24 months so that we can show we handled requests fairly.
