chunking - plugin for the CHUNKING SMTP extension (RFC 1830/3030)
The chunking plugin adds the SMTP CHUNKING extension from RFC 3030 ``SMTP Service Extensions for Transmission of Large and Binary MIME Messages'' to qpsmtpd.
This plugin was never tested in the wild, so I don't know how real clients behave ... :-)
Last time this plugin was tested was around qpsmtpd v0.40 or v0.43, it may not even run with >= 0.80
This plugin just accepts one parameter:
This enables the "BODY=BINARYMIME" MAIL FROM: parameter. If not present, it will reject a MAIL FROM:<email@example.com> BODY=BINARYMIME
with a 555 error (see RFC 1869).
Don't enable unless you're sure the backend MTA can handle this.
This plugin has never been tested with a real remote MTA
DON'T USE :P
