Chunking SMTP
RFC 3030defines the CHUNKING extension to SMTP. Chunking provides an alternative BDAT command that can be used instead of the normal DATA command to tranfer message content. BDAT uses octet counts rather than dot-stuffing and hence is more efficient. The  option, the default, tells the SMTP client to use BDAT if the server says it supports it. disables this usage.

The  option tells the SMTP server to announce support for and allow use of the CHUNKING extension. disables chunking support in the server. is the default.
