sender (i.e., the "QhOlt.domain" part) is saved and is appended to any addresses in the
message that do not already contam a domain spec. For example, a message
01
the
form:
From: ericGucbarpa
To: wnjOmonet, mckusick
will be modified to:
From: ericOucbarpa
To: wnjOmonet, mckusickQucbarpa
if

nlll
if
the
"c"
lag is defined in the mailer correspondinl to "ericQucbarpa."
Other lags are described in Appendix C.
The Sand R fields in the maller description are per-mailer rewritinl sets to be
applied to sender and recipient addresses respectively. These are applied after the
sending domain is appended and the general rewritinl sets (numbers one and two) are
applied, but before the output rewrite (ruleset four) is applied. A typical use is to
append the current domain to addresses that do not already have a domain. For exam-
ple, a header of the form:
From: eric
might be changed to be:
From: eric@ucbarpa
or
From: ucbvax!eric
depending on the domain it is beiDI shipped into. These sets can also be used to do
special purpose output rewriting in cooperation with ruleset four.
The E field defines the string to use as an end-ol-line indication. A string contain-
ing only newline is the default. The usual backslash escapes (\r, \n,
\1,
\b) may be
used.
Finally, an argv template is given as the E field. It may have embedded spaces.
If there is no argv with a
.u
macro in it, ,entlmail will speak SMTP to the mailer. If
the path name for this mailer is "(IPC)," the argv should be
IPC $h ( port)
where port
is
the optional port number to connect to.
For example, the specifications:
Mlocal, P=/bin/mail, F=rlsm 8==10, R==20, A==mail -d
Su
Mether,P=[IPC), F=meC, 8==11, R==21, A==IPC .h, M=I00000
specifies a mailer to do local delivery and a mailer for ethernet delivery. The Ilrst is
called "local," is located in the file "/bin/mail," takes a picky
-I'
lag, does local
delivery, quotes should be stripped from addresses, and multiple users can be delivered
at once; ruleset ten should be applied to sender addresses in the message and ruleset
twenty should be applied to recipient addresses; the argv to send to a message will be
the word "mail," the word "-d," and words containing the Dame 01 the receiving user.
If a
-I'
lag is inserted it will be between the words "mall" and "-d." The second mailer
is called "ether," it should be connected to via an IPC connection, it can handle multi-
ple users at once, connections should be deferred, and any domain from the sender
address should be appended to any receiver name without a domain; sender addresses
should be processed by ruleset eleven and recipient addresses by ruleset twenty-one.
There is a 100,000 byte limit
OD
messqes passed through this mailer.
