Messages with large attachments are often rejected by mail servers. Thunderbird works with web-based storage services to provide a mechanism for sending large file attachments.

Many email servers do not accept messages with large file attachments. The file size restriction varies depending on the mail server configuration. While you might be able to send a message with a large attachment, the receiving mail server might refuse to accept a message with a large attachment. This is all beyond the control of Thunderbird. Starting in Thunderbird 13, Thunderbird Filelink eliminates this problem by adding support for online storage services. It allows you to upload attachments to an online storage service and then replaces the attachment in the message with a link. The message recipient clicks the link to download the attachment. As additional benefits, sending and receiving large files is much faster and both you and the recipient will save disk space. Note that you can use Thunderbird Filelink in addition to [[how to use attachments|conventional attachments]]. For example, you can attach small files directly to a message and use Filelink for large attachments in the same message. The instructions below show how to configure and use Filelink with the [https://one.ubuntu.com/ Ubuntu One] online storage service. Other providers (including [https://www.yousendit.com/ YouSendIt] and [https://www.box.com/ Box]) are also supported. Simply substitute the service you are using as required. __TOC__ = Configuring Filelink = To use Filelink, you must first create a new account (or configure an existing account) with an online storage service provider. [[Template:optionspreferences]] Click on the {button Attachments} button, then click {button Outgoing}. Select the desired service provider from the drop-down list. Click the {button Add} button. Enter the username for your online storage account, or click {button Need an account?}. [[Image:ubuntu-account]] If you are creating a new account, a browser window will open that displays the service provider's registration page. Create an account as instructed. The service provider will send you a validation email message. Click the validation link in the message to activate your account. Enter your username (your email address) in the dialog shown above and enter your password when prompted. In the main configuration dialog, check {button Offer to share for files larger than...} and specify a file size (in megabytes) if you want Thunderbird to prompt you to use Filelink when a message attachment exceeds the specified size. = Using Filelink = When you attach a file to a message, if the file size exceeds the amount specified above, Thunderbird will offer to let you use Filelink: [[Image:filelink-prompt-ubuntu-one]] To force a file to be attached using Filelink (rather than relying on Thunderbird to determine if the attached file exceeds the specified size), you can click the down arrow next to the {button Attach} button on the message toolbar to access the Filelink menu option. Click the {button Link} button to upload the file to the online storage service provider. (Alternatively click {button Ignore} to attach the file as a [[how to use attachments|conventional attachment]].) [[Image:filelink attachment-ubuntu-one]] When the recipient receives the message, they will be informed that a file is linked to the message: [[Image:recipient filelink-ubuntu-one]] When the recipient clicks on the link in the message, some services like YouSendIt display an intermediary web page with an option to download the file. [[Image:filelink link]] Other services (like Ubuntu One) allow you to download the file immediately without an intermediate web page. = Filelink FAQ = Attachments that you send via Filelink are not stored on Mozilla servers. Each file storage service provider has its own privacy policy and terms of service. The file storage service provider has reviewed the Filelink feature to ensure that it is consistent with their policies. == Q: Does Mozilla know which provider the user has picked? == A: No. Mozilla is unaware of which provider has been selected by a user. Provider configuration is stored on the local machine. == Q: What storage services are currently supported? == A: As of Thunderbird 16, we have reached agreement with [https://www.box.com/ Box], [https://one.ubuntu.com/ Ubuntu One] and [https://www.yousendit.com/ YouSendIt] to integrate their services directly into Thunderbird. You can install support for more providers with add-ons, like: * [https://addons.mozilla.org/thunderbird/addon/dropbox-for-filelink/ Dropbox] * [https://addons.mozilla.org/thunderbird/addon/fileswapcom-filelink FileSwap.com] * [https://addons.mozilla.org/thunderbird/addon/dl-for-thunderbird/ DL for Thunderbird] may be the best if you prefer using your own server instead of relying on 3rd-party providers. * Last but not least, you can use Filelink with a WebDAV server with the [https://addons.mozilla.org/thunderbird/addon/webdav-for-filelink WebDAV for Filelink] add-on. == Q: Can the storage service view my attachments? == A: Unless you encrypt the file before uploading, the storage services will be able to view the file, as will anyone who obtains the link to the attachment. Users must decide on their own which service provider they trust with that responsibility. (Service providers generally explain your privacy rights in their terms of service.) Note that standard attachment functionality is also not encrypted. When you send an attachment the "normal" way, the file can be accessed by anyone that can access the message between your system and the recipients system (such as your email service provider). Filelink adds some security as file uploads to the storage service provider are sent via HTTPS, a secure protocol. == Q: How long will my file be available on the storage service provider's site? == A: The file will remain available on the storage service provider's site until you specifically delete it. Log in to the provider's website to view and delete the files in your storage space. == Q: Can you support service provider X or protocol Y? == A: We plan to support SpiderOak. We also have an "[http://blog.mozilla.org/thunderbird/ Up-for-grabs]" project available if anybody would like to add support for more services or protocols. Developer documentation for the Filelink feature can be found here: [https://developer.mozilla.org/en/Thunderbird/Filelink_Providers] == Q: I don't like the idea of storing my files with third-parties like this. Do regular attachments still work? == A: Regular email attachments still work the same as they always have. We've just given you the ability to choose to upload large attachments somewhere else, if you wish. Thunderbird's notion of a large file defaults to 1 MB, but can be customized in Thunderbird's Preferences. ([[Template:optionspreferences]]) The offer to upload can also be disabled entirely.
