Aws Lambda Ses Forwarder Versions Save

• Updating documentation about using Node.js 16 or 18 AWS Lambda runtimes.
• Updating tests to support Node.js 16 and later.

• Adding allowPlusSign configuration flag that when enabled ignores suffixes after a plus sign in email addresses. For example, an email addressed to
• Adding support for a catch all mapping by using "@" as the key. [email protected] is treated as if addressed to [email protected].
• Fixing handling of emails with less common header formats, such as where there is no space in the header after the colon and before the value.
• Updating aws-sdk dependency to match AWS Lambda environment.

• Removing Message-ID header from messages to fix InvalidParameterValue: Duplicate header 'Message-ID' errors.
• Fixing handling of multiline From headers to fix InvalidParameterValue: Extra route-addr errors.
• Updating documentation for SES endpoints.
• Updating aws-sdk dependency to match AWS Lambda environment.

• Added toEmail configuration for replacing the To header recipient to a defined email address.
• Changed AWS.S3() implementation to use signature version v4 for compatibility with S3 EU-based regions.

• Updated for the Node.js 4.3 runtime.
• Refactored steps to use promises.

Upgrade Notes

• The Node.js 4.3 Lambda runtime is required for this version.
• The arguments for the handler function have changed to match the Lambda runtime for Node.js 4.3 to include a callback function. If invoking the handler function, be sure to include the callback function provided in the Lambda runtime environment.
• Step functions that include asynchronous operations should return a promise, and are no longer provided a callback function as an argument. Upon successful completion of the step function, call Promise.resolve() with the data argument given to the step function. (Step functions that are synchronous should return the data argument.)

• Added capability to specify an email forwarding mapping based on a mailbox name across all domains (i.e. forward mail sent to foo@*).
• Added documentation to resolve "Could not write to bucket" error.
• Updating aws-sdk dependency to match AWS Lambda environment and other dev dependencies.

• Adding subjectPrefix configuration for adding a prefix string to the subject of forwarded email.
• Updating regex match for the Reply-To header to be case insensitive to support email sent with a Reply-to header.
• Fixing how libraries are loaded to improve performance.

• Adding capability to specify an email forwarding mapping that acts as a wildcard or catch-all for a domain.
• Converting the inbound recipient email address to lowercase before comparing to the forwarding map to handle case variations.
• Updating aws-sdk dependency to match AWS Lambda environment.

Upgrade Notes

• Email addresses and domain wildcard keys in the forwardMapping configuration object must be lowercase.

• Adding configuration option for a static "From" email address.

• Removing all DKIM-Signature headers to prevent errors when forwarding or DKIM verification issues when received.
• Updating the email processing to remove any Sender header and to only add a Reply-To header if one does not already exist.
