Summary

This is an extension of the Email::Simple module, to handle MIME

encoded messages. It takes a message as a string, splits it up

into its constituent parts, and allows you access to various

parts of the message. Headers are decoded from MIME encoding.

Update Information:

This update, to the latest upstream release, addresses an excessive memory use issue (CVE-2024-4140), which can cause denial of service when parsing multi-part MIME messages; the fix is the new $MAX_PARTS configuration, which limits how many parts will be considered for parsing, defaulting to 100.
