A filter that looks at a mailbox is not a hygiene report.

Answer A filter that looks at a mailbox is not a hygiene report. RFC 5490 describes Sieve extensions for checking mailbox status and reading mailbox metadata. The document is titled The Sieve Mail-Filtering Language -- Extensions for Checking Mailbox Status and Accessing Mailbox Metadata. A script looking at a folder is not an audit of a solo list. 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.

Cream stationery and a teal accent on a dark navy desk — A folder can be inspected. An audit of a list is a different job.

The note that started this: RFC 5490, The Sieve Mail-Filtering Language -- Extensions for Checking Mailbox Status and Accessing Mailbox Metadata, RFC 5490.

A rented send is one letter to someone else's list. Hygiene, in the desk sense that matters here, would be a question about those people. Are they the people the seller says they are. A script in this document looks at a folder. It can check mailbox status and read mailbox metadata. Status and metadata are about the mailbox. They are not a roll call of subscribers, and they are not proof anyone asked for the mail.

Ask what was checked about the people, and do not accept a folder status as the answer. When you discuss solo ad pricing, price the letter to the list, not a script's glance at a mailbox. If the seller's quality story is that a filter looked, you have heard about mail software. You still need the list, the sending domain, and the refund line on the order. A script cannot sign those lines.

What does RFC 5490 describe?

RFC 5490 describes Sieve extensions for checking mailbox status and reading mailbox metadata. A script looking at a folder is not an audit of a solo list. The document is titled The Sieve Mail-Filtering Language -- Extensions for Checking Mailbox Status and Accessing Mailbox Metadata.

Buyers should translate the offer into plain words and then reject the translation if it flatters them. Checked the mailbox means looked at mailbox status or mailbox metadata. It does not mean checked the people. If you wanted an audit of the solo list, ask for that audit in words about people. If the only paper you get is a script result about a folder, you were handed the wrong paper. Do not file it under hygiene.

Sellers should name the glance accurately. If a filter checks mailbox status or reads mailbox metadata, say that and stop. Do not title the output a hygiene report. The buyer will hear that the list was cleaned. You will have cleaned nothing about the people, or at least nothing this document describes. The refund line is a bad place to discover the difference.

A folder check was not called a hygiene report.
Mailbox status was not described as a verdict on the people.
You asked what, if anything, was checked about the list.
The sending domain and the refund line are written on the order.

Is a filter that looks at a mailbox a hygiene report?

No. A filter that looks at a mailbox is not a hygiene report. Checking mailbox status or reading mailbox metadata inspects the mailbox. It does not audit the people on a solo list.

Inspection of a folder can still be useful to the person who runs the mail software. Useful to them is not evidence for you. You are about to rent one letter. Your evidence is the identity of the list, the domain that sends, and the words of the creative. If the seller leans on it, they are leaning on an old specification. Let them lean. You name the list anyway.

The seller consequence of leaning is a buyer who thinks the work is done. They stop asking who the people are. You then send to whatever file you already had, under the halo of a report that never looked at them. If that file is not the file you described, the halo will not help. Say the script looked at a folder. Invite the question about people. A seller who can survive that question is easier to buy from than a seller who hides behind mailbox status.

What should the buyer name before paying?

A buyer still has to name the list, the sending domain, and the refund line on the order. A folder check is not a solo ad price, a rank, or proof that a stranger opted in.

Put the people on the order in language that does not mention the script. Put the domain next to them. Put the refund line under both, for the case where the send is not the send you approved. A fact about checking mailbox status does not set the price and does not rank the list. If the price moves because a filter can look at a folder, the price is tracking the wrong object. Bring it back to the letter.

Then decide whether the people, as named, are a list you are willing to rent. The script will not decide for you. Vendors worth a look on best solo ad vendors can talk about the file without waving a folder check. RFC 5490 stays a fact about mailbox status and mailbox metadata. A filter that looks at a mailbox is not a hygiene report.
