An anonymous login is not a subscriber.

Answer An anonymous login is not a subscriber. RFC 4505 describes an anonymous SASL mechanism. The document is titled Anonymous Simple Authentication and Security Layer (SASL) Mechanism. An anonymous session is not a list. Do not use anonymous login as a way to send mail. A rented letter needs a named sender and a named file. A session that withholds a name is the opposite of both, and it is not permission.

Cream stationery and a teal accent on a dark navy desk — A session without a name is not a reader.

The note that started this: RFC 4505, Anonymous Simple Authentication and Security Layer (SASL) Mechanism, RFC 4505.

Some pitches treat a login trick as if it were a file of readers. It is a way for a session to proceed without identifying a user. That is not a person who joined. If you buy solo ads for affiliate marketing, the offer assumes a reader who can act. An anonymous session does not hand you that reader. Refuse it as a sending plan before you talk about the creative. The creative cannot repair a missing name.

The document 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. Anonymous means unnamed. A subscriber is a person who asked. You cannot get from the first word to the second by citing the mechanism. If a seller offers anonymity, they are offering to hide the domain you were supposed to write on the order.

What does RFC 4505 describe?

RFC 4505 describes an anonymous SASL mechanism. The document is titled Anonymous Simple Authentication and Security Layer (SASL) Mechanism. An anonymous session is not a list.

SASL, in plain words, is a way software authenticates a session. This document describes the anonymous form of that idea. The session does not name a user. That can matter to an operator designing a service that allows nameless access. It does not matter as a story about buyers. Buyers are people. A nameless session has no person in it to opt in. Do not promote the mechanism into a file by speaking about it warmly.

Do not let anyone walk you through this as the way the solo goes out. The caution is short. Do not use anonymous login as a way to send mail. A seller who demonstrates it as the sending path is showing a path you should not buy. Ask them to stop, and ask for the sending domain by name. If the only path they have is the anonymous one, there is no order to sign.

Anonymous login is not offered as the way to send.
A session is not described as a subscriber.
The sending domain is a name, not a blank.
The list and the refund line are written on the order.

Should anyone use anonymous login to send a solo ad?

No. Do not use anonymous login as a way to send mail. An anonymous login is not a subscriber. A session without a name is not a file of people who asked for the letter.

The practical reason matches the definition. A complaint about a letter has to land on someone. An anonymous session is built to avoid naming a user. You would be paying for a send you cannot tie to the domain on the order, because the session withheld the name. Affiliate offers make that worse. The reader who dislikes the pitch needs a real sender, and so do you when the letter is not the letter you approved.

If you are the seller, do not recommend this mechanism as a courtesy or as a flourish on a solo. The buyer asked for a list and a domain. Give them those, or do not take the money. An anonymous login will not become a subscriber because you preferred not to name the account. The document does not say it will. You should not say it either.

What belongs on the order instead?

The list, the sending domain, and the refund line. RFC 4505 is not a solo ad price, a rank, or proof that a stranger opted in.

Name the list the letter will reach. Name the sending domain the reader will see. Name the refund line for a send that is not the send you ordered. None of those lines can be filled with the title of an authentication mechanism. If the draft order has the mechanism where the list should be, hand it back. A blank domain with a clever login is not a safer order. It is an order you cannot complain about later.

The buyer who wants a named file should buy solo ads from a seller who will put a real domain on the order. An anonymous login is not a subscriber. Do not pay a seller who needs it in order to send.
