Third, the F= delivery agent flags also tell sendmail how this particular delivery agent
behaves. For example, the F= delivery agent flag might specify that it perform final delivery
or require that it preserve uppercase for usernames.
Many delivery agent flags have special meaning to sendmail; others are strictly user-defined.
All the delivery agent flags are detailed at the end of this chapter (?§20.8 on page 759).
Note that whitespace characters cannot be used as delivery agent flags. Also note that
delivery agent flags OR together (they are really just bits), so they can be declared separately,
for clarity, as in the following:
F=D, # include Date: header if not present
F=F, # include From: header if not present
F=7, # strip the high-bit when delivering
* Note that a line feed is the same ASCII character as newline.

Or they can be declared all together, with no change in meaning or effect, like this:
F=DF7,
Note that the argument following the F= is optional, and an empty declaration is silently
ignored. Also note that the comma can be used as a delivery agent flag by prefixing it with a
backslash.
