A mailbox permission is not permission to mail the people.

Answer A mailbox permission is not permission to mail the people. RFC 4314 describes IMAP access control lists. The document is RFC 4314, titled IMAP4 Access Control List (ACL) Extension. A right to read or insert in a folder is not a right to advertise to those people. The right talks about a folder. The people, if their messages sit in that folder, did not grant your offer by being stored there. Access is not a yes. A solo still needs a list whose owner can say the readers asked, or it is the wrong product.

The note that started this: RFC 4314, IMAP4 Access Control List (ACL) Extension, RFC 4314.

This mix-up is expensive because it feels like paperwork you already finished. A login that can read a folder looks like authority. It is authority over a mailbox, which is a different desk. When you use solo ads for affiliate marketing, the authority you need is the list owner's right to send the letter, named on the order. A folder right does not substitute. A seller who offers the folder right as the permission is offering you someone else's filing cabinet.

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 buyer still has to name the list, the sending domain, and the refund line on the order. An access control list fills none of those blanks. A seller who opens with folder rights and never names the list is handing you a public document and calling it consent. Read the document if you want. Pay only for the order.

What does RFC 4314 describe?

RFC 4314 describes IMAP access control lists. The document is RFC 4314, titled IMAP4 Access Control List (ACL) Extension. A right to read or insert in a folder is not a right to advertise to those people.

An access control list tells mail software which operations a login may perform on a mailbox. Read and insert are examples of those operations. They let someone look at the folder or put a message in it. They do not introduce the login to the people, and they do not ask the people if they want a sales letter. A seller who says we can insert, so we can advertise, has jumped from a folder operation to a campaign. The jump is the whole problem. If the answer comes back as a folder right, stop, and do not pay.

• The order names permission from the list, not a folder right.
• Read or insert is not described as consent.
• The list, the sending domain, and the refund line are named.
• A login that can see a folder is not the audience.

Is a mailbox permission permission to mail the people?

No. A mailbox permission is not permission to mail the people. A right to read or insert in a folder is access to a folder. It is not consent to advertise.

Consent, for this buy, is the history that lets the list owner send one letter. A mailbox permission can exist with no history at all. An administrator can hold a right on a folder full of strangers. The strangers did not opt in to the administrator, and they did not opt in to you. If you would be ashamed to explain the right as your only yes, do not buy. Shame is a useful editor. The specification will not feel it for you.

If you have not paid, keep the money until the order names the list. If you have paid and the only yes was a folder right, the refund line is the next sentence. On the seller side, describe access as access. Describe a solo as one letter to someone else's list. The moment you use one word for both, you are selling a right you do not have. A careful seller loses that order on purpose.

Does a mailbox right prove the reader opted in?

No. 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 right on a folder does not remember a signup. It remembers an operation a login may perform. People who opted in opted in to a list, in a way you can ask about. The access list is the wrong place to look. It will not hand you a rank, and it will not set a price. Ask who is on the list. Ask which domain sends. Ask what the refund line says when a folder right was sold as consent, or when the list is not the list you named.

Price the object in your hand. A mailbox permission is a right on a folder. A solo is one letter to someone else's list. Read that difference before you buy solo ads. Pay for the letter only after the order names the list, the sending domain, and the refund line. An access list is not the invoice, and it is not the audience.
