A port number in a report is not the seller.

Answer A port number in a report is not the seller. RFC 6692 discusses source ports in abuse reports. A port is not an identity you can buy from. The document is RFC 6692, titled Source Ports in Abuse Reporting Format (ARF) Reports. That is a fact about mail software or about an old specification. It is not a solo ad price, a rank, or proof that a stranger opted in. A rented send is one letter to someone else's list. A source port mentioned in an abuse report is a detail of a report. It is not a counterparty, and it is not permission to mail anyone.

The note that started this: RFC 6692, Source Ports in Abuse Reporting Format (ARF) Reports, RFC 6692.

Abuse reports can carry a source port. A port is not a shop, not a brand, and not a list. You cannot ask a port who opted in. If the offer is solo ads for affiliate marketing, the letter still needs a named seller. A seller who identifies as a port has refused to be a counterparty. You buy from someone who can be named on an order.

A port looks like a clue, so the buyer chases it and forgets to ask for a name. If the only identity on offer is a source port, there is no one to make good when the letter is wrong. The specification discusses ports in reports. It does not mint sellers.

What does RFC 6692 discuss?

RFC 6692 discusses source ports in abuse reports. A port is not an identity you can buy from. The document is titled Source Ports in Abuse Reporting Format (ARF) Reports.

Discuss is as far as the desk needs to go. Reports of abuse can include a source port. That inclusion is a fact about the report format's use, not a directory of people who sell solo ads. You do not need to know how ports are chosen, and you should not treat a port as a trail to follow instead of a contract to write. A trail is not an order. An order has names.

Seller consequence: a buyer who only has a port cannot pay the right party, or pays and then cannot find anyone when the send is wrong. The seller who hid behind the port loses the sale or keeps money they cannot calmly defend. Buyer consequence: you hold a detail from a report and call it a relationship. The relationship does not exist until a seller, a list, and a domain are named. A source port names none of those. Put the report down and ask who is selling.

A source port is not written as the seller.
The list is a file with a name, not a port.
The sending domain is a domain, not a report detail.
The refund line names a party who can honor it.

Can a port number identify the seller?

No. A port number in a report is not the seller. That is a fact about mail software or about an old specification. It is not a solo ad price, a rank, or proof that a stranger opted in.

Identity for a purchase is a name you can put on an order and return to. A port number in a report is a detail that rode along in an abuse report. It does not say who owns a list. It does not say a stranger opted in. It does not say what a letter costs, and it is not a rank of vendors. If two sellers mentioned ports, you would still not know which file is which. Ask for the seller in words. If the words never come, you have no seller.

Do not invent what a port implies. The useful implication is negative. A port is not an identity you can buy from. A buyer who leaves with only a port has a fragment of a report. Fragments do not send the letter, and fragments do not refund.

What identity belongs on the order?

A buyer still has to name the list, the sending domain, and the refund line on the order. A source port names none of them. Pay a named seller, not a detail inside a report.

The list identifies the file. The domain identifies the sender the letter will use. The refund line identifies the remedy, which only works if there is a party attached to it. A source port identifies none of that. It identifies a detail the report format can carry. When the seller offers the port in place of their name, decline. You cannot hold a port to a send it never promised.

A port number in a report is not the seller. If you are ready to buy solo ads, buy them from a seller who will name the list, the domain, and the refund without pointing at a source port. RFC 6692 can discuss ports in abuse reports. It cannot be the vendor. Pay the name. Ignore the detail.
