CLI

nextmail imports

Every command in this namespace, with its arguments, flags and examples.

Commands

Bring an old mailbox across, straight from its mail server or from a Google Takeout, .mbox, .eml, .zip or .tgz export, with progress and a list of what did not come through.

Every command here also takes the global flags, such as --json, --profile and --dry-run. See the global flags

`openemail imports list`

List one page of mailbox imports

threads:readNeeds a sign-inAliasesls

Usage

nextmail imports list [flags]

Returns one page of the imports in the workspace, newest first. Each carries its status, the bytes read so far out of the total, and running counts of messages seen, imported, skipped as duplicates, left out by your options and not imported.

A key limited to particular addresses sees only imports into those addresses.

Add --all to walk every page: a table on a terminal, one JSON object per line when piped or with --ndjson, and one { items, hasMore, nextCursor } document with --json. --max <n> stops after that many items.

Flags

--address-id <value>: Only imports into this address.
--limit <n>: Rows per page, a whole number from 1 to 100. The server defaults to 25.
Default25
--cursor <value>: The nextCursor from the previous page, an import id. One that names no import this key can see is a 400 invalid_cursor.
--all: Fetch every page and stream the items as they arrive.
--max <n>: Stop after this many items. Implies --all.
--ndjson: Print every item as one JSON object per line. Implies --all

Examples

nextmail imports list

With optional flags

nextmail imports list --limit 50

Walk every page and stop after 100 items

nextmail imports list --all --max 100

One JSON object per line when piped

nextmail imports list --all > imports.ndjson

`openemail imports get`

Read one mailbox import

threads:readNeeds a sign-inAliasesshowview

Usage

nextmail imports get <id> [flags]

Resolves one import with its status, byte progress and counts. Poll it while status is queued or running; it settles on completed, failed or cancelled.

An import from a live mailbox has source imap or microsoft and carries remote, with the folders done out of the total and why it waits, and children, the contacts and calendar imports that came with it. Such an import can also wait: parked carries on by itself at remote.resumeAt, and needs-password stays until resume sends a new password. An import from files has source: file, remote: null and no children.

An id from another workspace answers exactly like one that never existed, with 404.

Arguments

<id>Required: Import id, imp_ followed by 24 hex characters.

Examples

nextmail imports get imp_3f9c2a7b1e4d8f60a5c7b92d

Print the raw JSON

`openemail imports create`

Create a mailbox import and get its upload plan

threads:writeNeeds a sign-inAliasesnewadd

Usage

nextmail imports create --address-id <value> --files <json|@file|-> [flags]
nextmail imports create --data <json|@file|-> [flags]

Creates an import into one address of the workspace and returns it with status: uploading. Each file is uploaded in parts of chunkBytes, files[i].chunks of them, through uploadChunk, and start then queues the import.

The import reads Google Takeout archives, .mbox files from Apple Mail, Thunderbird and most desktop apps, .eml files, and .zip or .tgz archives holding any of those, up to 100 GB a file and 50 files an import. Threads, dates and labels come across. Imported mail is quiet: it runs no rules, forwards, notifications, summaries or webhooks.

importFiles does create, upload and start in one call.

Flags

--address-id <value>: The address the mail belongs to. It must be an address this workspace owns and this key may act for. Required, here or in --data.
--files <json|@file|->: Each file as { name, bytes }, 1 to 50 of them, each at most 100 GB. JSON shaped as Array<ImportFileDescriptor>, inline or from a file with @path. Required, here or in --data.
--options-keep-inbox: Default true: mail that was in the old inbox lands in Inbox with its unread state. False files everything under Archive.
--options-include-spam: Default false.
--options-include-trash: Default false.
--data <json|@file|->: The whole body as JSON, inline, from a file with @path, or - for standard input. Flags override its keys.

Examples

nextmail imports create --address-id addr_2b7e --files @files.json

`openemail imports upload-state`

See which parts of the upload have arrived

threads:writeNeeds a sign-in

Usage

nextmail imports upload-state <id> [flags]

For each file, the indexes of the parts already stored, so an interrupted upload sends only what is missing. Empty once the import has left the uploading state.

Arguments

<id>Required: Import id, imp_ followed by 24 hex characters.

Examples

nextmail imports upload-state imp_3f9c2a7b1e4d8f60a5c7b92d

`openemail imports upload-chunk`

Upload one part of an import file

threads:writeNeeds a sign-in

Usage

nextmail imports upload-chunk <id> <file> <chunk> <data> [flags]

Stores one part of file file: the bytes from chunk * chunkBytes up to the next part. Every part is exactly chunkBytes long except the last, and a part of the wrong length is 400 bad_chunk. Sending a part again replaces it, so a failed part can simply be retried.

Arguments

<id>Required: Import id, imp_ followed by 24 hex characters.
<file>Required: The file index, in the order given to create.
<chunk>Required: The part index, from 0.
<data>Required: The part as a Blob, Uint8Array or ArrayBuffer.

`openemail imports start`

Queue an import once its files are uploaded

threads:writeNeeds a sign-in

Usage

nextmail imports start <id> [flags]

Checks that every part of every file has arrived, recognises each file's format and queues the import. A file still missing parts is 412 missing_chunks, and a file that is not an archive or a mailbox is 400 unsupported_file. Calling it on an import that has already left uploading returns it unchanged.

Arguments

<id>Required: Import id, imp_ followed by 24 hex characters.

`openemail imports import-files`

Create, upload and start an import in one call

threads:writeNeeds a sign-in

Usage

nextmail imports import-files --address-id <value> --files <path> [flags]
nextmail imports import-files --data <json|@file|-> [flags]

Creates the import, uploads every file part by part and starts it, reporting progress through onProgress. Pass each file as a Blob, Uint8Array or ArrayBuffer; parts are sliced from it, so a Blob backed by a file on disk is never read into memory at once.

It resolves once the import is queued. Poll get to follow it.

Flags

--address-id <value>: The address the mail belongs to. Required, here or in --data.
--files <path>Repeatable: Each file as { name, data }. Required, here or in --data.
--options <json|@file|->: keepInbox, includeSpam and includeTrash, as for create. JSON shaped as ImportOptions, inline or from a file with @path.
--data <json|@file|->: The whole input as JSON, inline, from a file with @path, or - for standard input. Flags override its keys.

Examples

nextmail imports import-files --address-id addr_2b7e --files ./takeout.zip

`openemail imports discover-mailbox`

Find the mail server for an address

threads:writeNeeds a sign-in

Usage

nextmail imports discover-mailbox <email> [flags]

Looks up where the mailbox behind an address lives, so an import can connect to it. It tries the providers Nextmail knows, then who receives mail for the domain, then Mozilla's public list of mail settings, then the domain's own _imaps._tcp record. Nothing is stored and no sign-in is attempted.

server is null when nothing was found: ask for the host and port and pass them to checkMailbox. signIn says what the mailbox takes. app-password and password are what checkMailbox and connectMailbox send. An Outlook.com or Microsoft 365 mailbox answers microsoft, which only the Microsoft sign-in on the Migrations page of the app can open.

Arguments

<email>Required: The address of the old mailbox.

Examples

nextmail imports discover-mailbox [email protected]

nextmail imports discover-mailbox [email protected] --json

API: GET /imports/mailbox-settings

`openemail imports check-mailbox`

Check a mailbox before importing it

threads:writeNeeds a sign-in

Usage

nextmail imports check-mailbox --email <value> --password <value> [flags]
nextmail imports check-mailbox --data <json|@file|-> [flags]

Signs in to the old mailbox over IMAP, lists its folders and counts the messages, then signs out. Nothing is stored, the password is not kept and the old mailbox is not changed. Use it to show what an import would bring before starting one.

Leave host out to have the server looked up from the address, as discoverMailbox does. Only port 993 with TLS, or port 143 with STARTTLS, is accepted. Each person may make 10 sign-in attempts an hour across checkMailbox, connectMailbox and resume, and every refused sign-in reads the same, whatever the reason.

Flags

--email <value>: The address of the old mailbox. Required, here or in --data.
--password <value>: The password of the old mailbox, or an app password where discoverMailbox answers signIn: app-password. Pass - to read it from standard input, or @path to read it from a file, so it stays out of your shell history. Required, here or in --data.
--host <value>: The IMAP host, such as imap.example.com. It has to be a public host. Left out, the server is looked up from the address.
--port <n>: 993 or 143, read only with host. Left out, it follows security: 993 for tls and 143 for starttls.
--security <value>: tls or starttls, read only with host. Left out, it follows port, and is tls when both are left out.
--username <value>: The name to sign in with. Left out, it is the username that discoverMailbox answers, usually the address.
--data <json|@file|->: The whole body as JSON, inline, from a file with @path, or - for standard input. Flags override its keys.

Examples

nextmail imports check-mailbox --email [email protected] --password @password.txt

`openemail imports connect-mailbox`

Import a live mailbox

threads:writeNeeds a sign-in

Usage

nextmail imports connect-mailbox --address-id <value> --email <value> --password <value> [flags]
nextmail imports connect-mailbox --data <json|@file|-> [flags]

Starts copying an old mailbox into one address, straight from its mail server. It signs in once to check the password, keeps the password sealed until the import finishes and for 30 days at most, and queues the import. Poll get for progress.

The old mailbox is only ever read. Folders become labels, read and starred state come across, and a message the address already holds is skipped, so running an import twice adds nothing. A Gmail mailbox is read from All Mail, with its labels. An import waits by itself when the old provider slows it down, such as Gmail's daily download limit, and carries on from the same folder afterwards: status is parked and remote.resumeAt says when. If the password stops working, status is needs-password until resume sends a new one.

contacts and calendars bring those across too where the provider offers them, which needs contacts:write and calendar:write as well. They arrive as contacts and calendar imports of their own, listed in children. --rerun-of names a finished import of the same mailbox, at most 30 days old, so only mail that arrived since is fetched. One import may run into an address at a time.

Flags

--address-id <value>: The address the mail belongs to. It must be an address this workspace owns and this key may act for. Required, here or in --data.
--email <value>: The address of the old mailbox. Required, here or in --data.
--password <value>: The password of the old mailbox, or an app password where discoverMailbox answers signIn: app-password. Pass - to read it from standard input, or @path to read it from a file, so it stays out of your shell history. Required, here or in --data.
--host <value>: The IMAP host, such as imap.example.com. It has to be a public host. Left out, the server is looked up from the address.
--port <n>: 993 or 143, read only with host. Left out, it follows security: 993 for tls and 143 for starttls.
--security <value>: tls or starttls, read only with host. Left out, it follows port, and is tls when both are left out.
--username <value>: The name to sign in with. Left out, it is the username that discoverMailbox answers, usually the address.
--options-keep-inbox: Default true: mail that was in the old inbox lands in Inbox with its unread state. False files everything under Archive.
--options-include-spam: Default false.
--options-include-trash: Default false.
--contacts: True brings the address book across too, where the provider offers it. Needs contacts:write.
--calendars: True brings the calendars across too, where the provider offers them. Needs calendar:write.
--rerun-of <value>: The id of a finished import of the same mailbox, at most 30 days old. Only mail that arrived since is fetched.
--data <json|@file|->: The whole body as JSON, inline, from a file with @path, or - for standard input. Flags override its keys.

`openemail imports resume`

Resume a waiting mailbox import

threads:writeNeeds a sign-in

Usage

nextmail imports resume <id> [flags]

Carries on an import from a live mailbox that is waiting. One with status: parked is queued again at once, without a body. One with status: needs-password needs the new password, which is checked against the old mailbox before the import is queued. It picks up at the folder and message it stopped at.

An import that came from a Microsoft sign-in is resumed by signing in again on the Migrations page of the app.

Arguments

<id>Required: Import id, imp_ followed by 24 hex characters.

Flags

--password <value>: The new password of the old mailbox. Required when status is needs-password. Pass - to read it from standard input, or @path to read it from a file, so it stays out of your shell history.
--data <json|@file|->: The whole body as JSON, inline, from a file with @path, or - for standard input. Flags override its keys.
