| Add a blank line after message |
V8.6 and above |
Some Unix mailbox
formats require a blank line at the end of one message and before the
start of the next message. If your local version of
/bin/mail does not assure that this blank line
exists, you can use the F=b delivery agent flag.
If this delivery agent flag is specified and if the message being
sent to the delivery agent lacks a blank line at the end,
sendmail adds one. This delivery agent flag is
also appropriate for use with the *file* delivery
agent.
