client.ConnectedMailboxes
Every method in this namespace: its signature, its parameters, what it returns and an example.
Methods
Mailboxes that stay at Gmail, Yahoo, iCloud or another provider and are worked from Nextmail: find their mail servers, connect one with an app password, see whether it syncs, pause, resume or rename it, give it a new password, sync it now and disconnect it. New mail is copied in, what is done to it here goes back to the provider, and mail written as its address is sent through the provider.
ConnectedMailboxes.ListAsync
List the connected mailboxes
Task<IReadOnlyList<JsonObject>> ListAsync( string? apiKey = null, CancellationToken cancellationToken = default)Returns every mailbox connected to the workspace in one list, newest first. The list comes whole and is never paged. A connected mailbox stays at its provider, such as Gmail or Yahoo, and is worked from Nextmail: its new mail is copied in, what is done to it here goes back to the provider, and mail written as its address is sent through the provider.
status is active while it syncs and sends, paused while a person stopped it, needs-sign-in when the provider stopped accepting its password, and failing when the last five syncs failed and it keeps trying less often.
Parameters
apiKeystring?Overrides the client's API key for this call only.
cancellationTokenCancellationTokenCancels the request.
Returns
A list of JsonObject items. Each item has id, addressId, email, label, provider, method, status, pauseReason, lastError, lastSyncedAt, createdAt, connectedBy, username, imap, smtp and historyImportId.
Example
var mailboxes = await client.ConnectedMailboxes.ListAsync(); foreach (var mailbox in mailboxes){ Console.WriteLine($"{mailbox["email"]} {mailbox["status"]} {mailbox["lastSyncedAt"]}");}Notes
A key or an app limited to particular addresses sees only the mailboxes of those addresses.
lastErroris what the mail server said the last time something went wrong, and null while nothing is wrong.Read only, so the SDK retries it after a network failure like any other read.
Also available in
ConnectedMailboxes.GetAsync
Read one connected mailbox by id
Task<JsonObject> GetAsync( string id, string? apiKey = null, CancellationToken cancellationToken = default)Looks up one connected mailbox and returns it in the same shape as a row of ListAsync: whether it is syncing, when it last finished, and what went wrong if it did not.
Parameters
idstringRequiredConnected mailbox id such as
cmb_5c1e9a7b3d2f48e6a0b4c7d1, asListAsyncreturns it.apiKeystring?Overrides the client's API key for this call only.
cancellationTokenCancellationTokenCancels the request.
Returns
A JsonObject with id, addressId, email, label, provider, method, status, pauseReason, lastError, lastSyncedAt, createdAt, connectedBy, username, imap, smtp and historyImportId.
Example
using Nextmail.Constants; var mailbox = await client.ConnectedMailboxes.GetAsync("cmb_5c1e9a7b3d2f48e6a0b4c7d1"); if ((string?)mailbox["status"] == ConnectedMailboxStatuses.NeedsSignIn){ Console.WriteLine($"{mailbox["email"]} needs a new app password: {mailbox["lastError"]}");}Notes
A missing mailbox, or one whose address the caller cannot reach, throws an
NextmailApiExceptionwhoseIsNotFoundis true and whoseCodeisconnected_mailbox_not_found.Read only, so the SDK retries it after a network failure like any other read.
Also available in
ConnectedMailboxes.DiscoverAsync
Find the mail servers for a mailbox
Task<JsonObject> DiscoverAsync( string email, string? apiKey = null, CancellationToken cancellationToken = default)Looks up where the mailbox behind an address lives and what it signs in with, so the right password can be asked for before ConnectAsync. Nothing is stored and no sign-in is attempted.
signIn is app-password for Gmail, Yahoo, iCloud and the other providers that want one, password where the everyday password works, and microsoft for Outlook.com and Microsoft 365, which only the Microsoft sign-in in the app can connect. imap is null when nothing was found: pass host to ConnectAsync. smtp is null when the outgoing server is found while connecting, or can be passed as smtpHost.
Parameters
emailstringRequiredThe address of the mailbox.
apiKeystring?Overrides the client's API key for this call only.
cancellationTokenCancellationTokenCancels the request.
Returns
A JsonObject with email, provider, signIn, imap and smtp.
Example
using Nextmail.Constants; var settings = await client.ConnectedMailboxes.DiscoverAsync("[email protected]"); if ((string?)settings["signIn"] == MailboxSignIns.AppPassword){ Console.WriteLine($"Make an app password at {settings["provider"]}");} Console.WriteLine(settings["imap"] is null ? "Ask for the IMAP host" : $"Mail is read from {settings["imap"]?["host"]}");Notes
Something that is not an email address is a 400
mailbox_address_invalid.Too many lookups in an hour is a 429
mailbox_checks_limited.A GET is retried automatically on network failure and on 408, 500, 502, 503 and 504 responses, up to the client
MaxRetries, and on a 429 only when it carries aRetry-Afterof a minute or less.
Also available in
ConnectedMailboxes.ConnectAsync
Connect a mailbox at another provider
Task<JsonObject> ConnectAsync( IReadOnlyDictionary<string, object?> body, string? apiKey = null, CancellationToken cancellationToken = default)Connects a mailbox that stays at Gmail, Yahoo, iCloud or another provider, so its address becomes an address of the workspace while its mail stays where it is. It signs in to the incoming and the outgoing server with the password, keeps the password sealed, adds the address and starts copying new mail in within a minute.
From then on read, starred, archived, spam and deleted go back to the provider, and mail written as the address goes out through the provider, so it lands in its Sent folder too. With importHistory set to true it also starts an import of the mail already in the mailbox, which Imports.GetAsync follows by historyImportId.
Most providers want an app password, made in the account's security settings, not the everyday password. Leave host and smtpHost out to have the servers found from the address, as DiscoverAsync shows.
Parameters
emailstringRequiredThe address of the mailbox, such as
[email protected].passwordstringRequiredThe app password of the mailbox, or its password where the provider has no app passwords.
hoststringThe IMAP server. Left out, it is looked up from the address.
portintThe IMAP port: 993 with TLS, or 143 with STARTTLS.
securitystringHow the IMAP connection is encrypted:
tlsorstarttls.usernamestringThe name to sign in with, when it is not the address.
smtpHoststringThe SMTP server mail is sent through. Left out, it is found.
smtpPortintThe SMTP port: 465 with TLS, or 587 with STARTTLS.
smtpSecuritystringHow the SMTP connection is encrypted:
tlsorstarttls.labelstringA name for the address, shown beside it in the app, up to 120 characters.
importHistoryboolWhether to copy the mail already in the mailbox as well. Left out, only mail that arrives from now on comes in.
apiKeystring?Overrides the client's API key for this call only.
cancellationTokenCancellationTokenCancels the request.
Returns
A JsonObject with a new id, the addressId the mailbox appears as, and status active.
Example
var mailbox = await client.ConnectedMailboxes.ConnectAsync(new Body{ ["email"] = "[email protected]", ["password"] = Environment.GetEnvironmentVariable("GMAIL_APP_PASSWORD"), ["label"] = "Ada (Gmail)", ["importHistory"] = true,}); Console.WriteLine($"{mailbox["id"]} {mailbox["addressId"]} {mailbox["status"]}");Notes
Mail from a connected address is sent through the provider, never through Nextmail's servers, and only to people. Broadcasts, automations, sign-up forms and
Emails.SendAsyncwith an API key refuse it as the sender.A wrong password is a 400
mailbox_login_failed, and an outgoing server that refuses it a 400connected_mailbox_send_sign_in_failed. No server found is a 400mailbox_settings_unknownorconnected_mailbox_send_server_unknown. An Outlook.com or Microsoft 365 mailbox is a 400mailbox_uses_microsoft: connect it with the Microsoft sign-in in the app, and manage it from here after that.An address whose mail already comes to Nextmail is a 400
connected_mailbox_domain_hosted. A mailbox already connected here is a 409connected_mailbox_already_connected, and one connected to another workspace a 409connected_mailbox_connected_elsewhere.The address counts toward the addresses of the plan, and a full plan is a 422
workspace_limit_reached. A key or an app limited to particular addresses or domains is refused with 422capability_unsupported.Each person may make 10 sign-in attempts an hour across this call,
UpdateAsyncwith a password and theImportscalls that sign in to a mailbox, and more is a 429mailbox_checks_limited.Not retried automatically: a retry after a lost response answers 409
connected_mailbox_already_connected, which then means the first call went through.
Also available in
ConnectedMailboxes.UpdateAsync
Pause, resume or rename a connected mailbox, or give it a new password
Task<JsonObject> UpdateAsync( string id, IReadOnlyDictionary<string, object?> patch, string? apiKey = null, CancellationToken cancellationToken = default)Changes a connected mailbox and returns it as it is now. Send only what changes: a field left out stays as it is.
paused set to true stops syncing and sending through the mailbox, and paused set to false starts both again. The mail already copied in stays either way. password gives it a new app password after the provider stopped accepting the old one: it is checked against both servers before it is kept, and a mailbox that needed signing in starts syncing again. label renames its address, and null clears the name.
Parameters
idstringRequiredConnected mailbox id such as
cmb_5c1e9a7b3d2f48e6a0b4c7d1, asListAsyncreturns it.pausedboolTrue pauses the mailbox and false resumes it. Left out, it stays as it is.
passwordstringA new app password. Left out, the password stays.
labelstringA name for the address, up to 120 characters, or null to clear it. Left out, the name stays.
apiKeystring?Overrides the client's API key for this call only.
cancellationTokenCancellationTokenCancels the request.
Returns
A JsonObject with the unchanged id, and status, pauseReason and label as they are now.
Example
var mailbox = await client.ConnectedMailboxes.UpdateAsync("cmb_5c1e9a7b3d2f48e6a0b4c7d1", new Body{ ["password"] = Environment.GetEnvironmentVariable("GMAIL_APP_PASSWORD"),}); Console.WriteLine(mailbox["status"]);Notes
A mailbox that needs signing in cannot be paused or resumed until it has a new password, or until a
microsoftone is signed in again in the app.A password the mail server refuses is a 400
mailbox_login_failedorconnected_mailbox_send_sign_in_failed, and the old one stays. Amicrosoftmailbox has no password to change, which is a 400connected_mailbox_no_password: it signs in again in the app. A missing mailbox is a 404connected_mailbox_not_found.A value of the wrong type or length is 422
invalid_parameter, and a key the patch does not take 422unknown_parameter.Not retried automatically. Read it with
GetAsyncbefore you try again.
Also available in
ConnectedMailboxes.SyncAsync
Sync a connected mailbox now
Task<JsonObject> SyncAsync( string id, string? apiKey = null, CancellationToken cancellationToken = default)Asks for a sync straight away instead of at the next interval, and returns the mailbox at once. The sync follows within seconds, and lastSyncedAt moves when it has finished.
A mailbox is synced every 30 seconds while mail comes in, and less often after it has been quiet for a while, down to every five minutes. A paused mailbox, or one that needs signing in, is not synced.
Parameters
idstringRequiredConnected mailbox id such as
cmb_5c1e9a7b3d2f48e6a0b4c7d1, asListAsyncreturns it.apiKeystring?Overrides the client's API key for this call only.
cancellationTokenCancellationTokenCancels the request.
Returns
A JsonObject: the mailbox as it was when the sync was asked for.
Example
var mailbox = await client.ConnectedMailboxes.SyncAsync("cmb_5c1e9a7b3d2f48e6a0b4c7d1"); Console.WriteLine($"A sync starts within seconds. The last one finished at {mailbox["lastSyncedAt"]}");Notes
A missing mailbox is a 404
connected_mailbox_not_found.Asking twice does no harm, so the SDK retries this call after a network failure.
Also available in
ConnectedMailboxes.DisconnectAsync
Disconnect a mailbox
Task<JsonObject> DisconnectAsync( string id, string? apiKey = null, CancellationToken cancellationToken = default)Stops syncing and sending through the mailbox, forgets its password and removes its address from the workspace. The mail already copied in stays in Nextmail, and nothing is changed at the provider. An import of its history that is still running is cancelled.
To stop it for a while and keep it, use UpdateAsync with paused set to true. To use it again later, start over with ConnectAsync.
Parameters
idstringRequiredConnected mailbox id such as
cmb_5c1e9a7b3d2f48e6a0b4c7d1, asListAsyncreturns it.apiKeystring?Overrides the client's API key for this call only.
cancellationTokenCancellationTokenCancels the request.
Returns
A JsonObject with object set to connected_mailbox, the id, the addressId and the email of the mailbox, and deleted set to true.
Example
var removed = await client.ConnectedMailboxes.DisconnectAsync("cmb_5c1e9a7b3d2f48e6a0b4c7d1"); Console.WriteLine($"{removed["email"]} deleted: {removed["deleted"]}");Notes
A missing mailbox is a 404
connected_mailbox_not_found.The SDK retries this call after a network failure. When the first attempt went through and only its answer was lost, the retry answers 404
connected_mailbox_not_found, which then means the mailbox is disconnected.
