nodemailer

• Added new message transport option normalizeHeaderKey(key)=>normalizedKey for custom header formatting

• Added sponsors section to README
• enclose encodeURIComponent in try..catch to handle invalid urls

• Better handling of unexpectedly dropping connections

• Changed default behavior for attachment option contentTransferEncoding. If it is unset then base64 encoding is used for the attachment. If it is set to false then previous default applies (base64 for most, 7bit for text)

• Fixed a confict with Electron.js where timers do not have unref method

• Added new mail object method mail.normalize(cb) that should make creating HTTP API based transports much easier

• Expose streamed messages size and timers in info response

• Allow generating preview links without calling createTestAccount first

• No actual changes. Needed to push updated README to npmjs

• Fixed JSONTransport attachment handling

• Added new methods createTestAccount and getTestMessageUrl to use autogenerated email accounts from https://Ethereal.email

• Fixed issue with LMTP and STARTTLS

• License changed from EUPLv1.1 to MIT

• Fixed invalid List-* header generation

• Emit an error if STARTTLS ends with connection being closed

• Expose last server response for smtpConnection

• Fixed SES transport, added missing response value

• Fixed DKIM calculation for empty body
• Ensure linebreak after message content. This fixes DKIM signatures for non-multipart messages where input did not end with a newline

• Fixed missing transport.verify() methods for SES transport

• Added missing error handlers for Sendmail, SES and Stream transports. If a messages contained an invalid URL as attachment then these transports threw an uncatched error

• Fixed missing transport.on('idle') and transport.isIdle() methods for SES transports

• Added built-in transport for AWS SES. Docs
• Updated stream transport to allow building JSON strings. Docs
• Added new method mail.resolveAll that fetches all attachments and such to be able to more easily build API-based transports

• Fixed a bug with OAuth2 login where error callback was fired twice if getToken was not available.

• Fixed a bug where Nodemailer threw an exception if disableFileAccess option was used
• Added FLOSS exception declaration

• Initial version of Nodemailer 3

This update brings a lot of breaking changes:

• License changed from MIT to EUPL-1.1. This was possible as the new version of Nodemailer is a major rewrite. The features I don't have ownership for, were removed or reimplemented. If there's still some snippets in the code that have vague ownership then notify mailto:andris@kreata.ee about the conflicting code and I'll fix it.
• Requires Node.js v6+
• All templating is gone. It was too confusing to use and to be really universal a huge list of different renderers would be required. Nodemailer is about email, not about parsing different template syntaxes
• No NTLM authentication. It was too difficult to re-implement. If you still need it then it would be possible to introduce a pluggable SASL interface where you could load the NTLM module in your own code and pass it to Nodemailer. Currently this is not possible.
• OAuth2 authentication is built in and has a different configuration. You can use both user (3LO) and service (2LO) accounts to generate access tokens from Nodemailer. Additionally there's a new feature to authenticate differently for every message – useful if your application sends on behalf of different users instead of a single sender.
• Improved Calendaring. Provide an ical file to Nodemailer to send out calendar events.

And also some non-breaking changes:

• All dependencies were dropped. There is exactly 0 dependencies needed to use Nodemailer. This brings the installation time of Nodemailer from NPM down to less than 2 seconds
• Delivery status notifications added to Nodemailer
• Improved and built-in DKIM signing of messages. Previously you needed an external module for this and it did quite a lousy job with larger messages
• Stream transport to return a RFC822 formatted message as a stream. Useful if you want to use Nodemailer as a preprocessor and not for actual delivery.
• Sendmail transport built-in, no need for external transport plugin

See Nodemailer.com for full documentation

• Bumped mailcomposer that generates encoded-words differently which might break some tests

• Added new options disableFileAccess and disableUrlAccess
• Fixed envelope handling where cc/bcc fields were ignored in the envelope object

• Removed shrinkwrap file. Seemed to cause more trouble than help

• Fixed outdated shrinkwrap file

• Bumped mailcomposer module to allow using false as attachment filename (suppresses filename usage)
• Added NTLM authentication support

• Bumped smtp transport modules to get newest smtp-connection that fixes SMTPUTF8 support for internationalized email addresses

• Bumped mailcomposer to have better support for message/822 attachments

• Fixed a bug with attachment filename that contains mixed unicode and dashes
• Added built-in support for proxies by providing a new SMTP option proxy that takes a proxy configuration url as its value
• Added option transport to dynamically load transport plugins
• Do not require globally installed grunt-cli

• Fixed a bug in SMTP requireTLS option that was broken

• Removed the need to use clone dependency
• Added new method verify to check SMTP configuration
• Direct transport uses STARTTLS by default, fallbacks to plaintext if STARTTLS fails
• Added new message option list for setting List-* headers
• Add simple proxy support with getSocket method
• Added new message option textEncoding. If textEncoding is not set then detect best encoding automatically
• Added new message option icalEvent to embed iCalendar events. Example here
• Added new attachment option raw to use prepared MIME contents instead of generating a new one. This might be useful when you want to handcraft some parts of the message yourself, for example if you want to inject a PGP encrypted message as the contents of a MIME node
• Added new message option raw to use an existing MIME message instead of generating a new one
