APPENDIX C
MAILER FLAGS
The following Hags may be set in the mailer deaeriptioa.
f
The mailer wants a -I Irom 881, but only if this is a network forward operation (i.e., the
mailer will give an error if the executinl user does not have special permissiou).
r
Same as I, but sends a
-I'
8al.
S
Don't reset the userid before caUinl the mailer. This would be used in a seeure environment
where
8endmail
ran as root. This could be used to avoid forged addresses. This 8al is
suppressed if given (rom an "unsafe" environment (e.l, a user's mail.cf file).
n Do not insert a UNIX-style "From" line on the front of the messaae.
This mailer is local (i.e., final delivery will be performed).
s Strip quote characters of( of the addre. before calling the mailer.
m This mailer can send to multiple usen on the same host in one transaction. When a
tu
macro occun in the argv part of the mailer definition, that field will be repeated as necessary
for all qualirying users.
F This mailer wan ts a "From:" header line.
D This mailer wants a "Date:" header line.
M This mailer wants a "Message-Id:" header line.
x This mailer wants a "Full-Name:" header line.
P This mailer wants a "Return-Path:" line.
u Upper case should be preserved in user names for this mailer.
h Upper case should be preserved in b08t names for this mailer.
A This is an Arpanet-compatible mailer, and all appropriate modes should be set.
U This mailer wants Unix-style "From" lines with the ugly UUCP-style "remote from
<host>" on the end.
e This mailer is expensive to connect to,
80
try to avoid connectinl normally; any necessary
connection will occur during a queue run.
X This mailer want to use the hidden dot algorithm as specified in RFC821; basically, any line
beginning with a dot will have an extra dot prepended (to be stripped at the other end).
This insures that lines in the message containinl a dot will not terminate the message prema.-
turely.
L Limit the line lengths
88
specified in RFC821.
P Use the return-path in the SMTP "MAIL FROM:" command rather than just the return
address; although this is required in RFC821, mU1 hosts do not process return paths prop-
erly.
I This mailer will
be
speaking SMTP to another
,endmtJil -
as such it can use special protocol
features. This option
is
not required (i.e., if this option is omitted the transmi.ion wiD still
operate successfully, although perhaps not as efficiently
88
possible).
C It mail is received from a mailer with this 8al set, any addresses in the header that do not
have an at sign ("0") after beinl rewritten by ruleset three will have the "Qdomain" clause
from the sender tacked on. This allows mail with headen of the form:
Sendmall installation and Operation Guld.
