Comments: header is used to place explanatory text
into the header portion of an email. The field portion of the
Comments: header can contain arbitrary text.
One possible use for a Comments: header would be
to notify recipients that one person is replying to mail for another:
Comments: Ben is in France for the next month or
so gathering information for the meeting.
I am handling his mail while he is away.
The Comments: header should
rarely be declared in the configuration file. If
it is, it should be prefixed with appropriate
H?B?Comments: Local delivery is experimentally being handled
by a new program. Complaints to root.
This comment is included only in headers that are delivered via the
local delivery agent because that delivery agent
is the only one to include the F=B flag:
Mlocal, P=/bin/mail, F=rlsDFMmnPB, S=10, R=20, A=mail -d $u
This declaration causes the new Comment: header to
be added to the mail message.
