2.3.4.31 Channel Protocol Selection (smtp, nosmtp)

These options specify whether or not a channel supports the SMTP protocol and what type of SMTP line terminator PMDF expects to see as part of that protocol. nosmtp means that the channel doesn't support SMTP; all the rest of these keywords imply SMTP support.

The selection of whether or not to use the SMTP protocol is implicit for most channels; the correct protocol is chosen by the use of the appropriate channel program or programs.

The keyword smtp is mandatory for all SMTP channels.

The keywords smtp_cr, smtp_crlf, smtp_crorlf, and smtp_lf may be used on SMTP channels to specify what character sequences to accept as line terminators. smtp_crlf means that lines must be terminated with a carriage return (CR) line feed (LF) sequence. smtp_crorlf or smtp means that lines may be terminated with any of a carriage return (CR), or a line feed (LF) sequence, or a full CRLF. smtp_lf means that a LF without a preceeding CR will be accepted. Finally, smtp_cr means that a CR will be accepted without a following LF. It is normal to use CRLF sequences as the SMTP line terminator, and this is what PMDF itself always generates; this option only affects PMDF's handling of incoming material.
