Binaryclient, nobinaryclient, binaryserver, nobinaryserver Channel Options

Binary SMTP
The BINARYMIME SMTP extension defined in RFC 3030 provides support for transferring messages containing binary parts without encoding over SMTP.

New in MS 8.0, the  source channel option enables this extension in the SMTP server. The  source channel option disables it, and is the default. Note that   enables the BDAT command for BODY=BINARYMIME messages even if    is not in effect.

Binary messages submitted using this extension are immediately converted by the MTA to regular 8bit MIME so the format of messages in the MTA queues is not affected, nor is the format of messages that are passed through the spam filter interface.

The BINARYMIME extension is not presently supported by the SMTP client, so the  and   channel  options are currently unimplemented.
