1.1. Special Head .. LID.
Several header linea have special interpretations defined by the cODlluration lie.
Others have interpretations built into .entlmtJil that canDot be chaDled without chaDlinl
the code. These builtins are described here.
1.1.1. Return-Reeelpt-Tol
II this header is seDt,
a
measale wiD
be
seDt to any specified addreeeea wheD the
final delivery is complete. it the mailer haa the 1 8al (local delivery) set in the mailer
descriptor.
2.8.2. Erro .... TOI
II errors occur anywhere durinl Processinl, this header wiD cause error meaalea
to go to the listed addresses rather than to the Bender. This
is
intended tor mailin,
lists.
2.8.3. Apparentl7-Tol
If a mess3le comea in with no recipients listed in the messale (in a To:, Cc:, or
Bcc: line) then sendmtJil will add an "Apparently-To:" header line for
any
recipients it
is aware of. This is not put in as a standard recipient IiDe to warn any recipieDts that
the list is not complete.
At least ODe recipient line is required UDder RFC 822.
3. ARGUMENTS
The complete list at arguments
to
.entimtJil is described iD detail
in
Appendix A. Some
important arguments are described here.
3.1. Queue Interval
The amount at time between torkinl a procell to rUD through the queue is defined by
the
-q
Bag. II you run in mode , or a this
CaD
be
relatively larle, since it will only
be
relevant when a host that was down comea back up. If you rUD in
q
mode it should
be
relatively short, since it defines the maximum amouDt at time that a meaale may sit in
the queue.
3.1. Daemon Mode
If you allow incominl mail over an IPC connection, you should have a daemon run-
ning. This should be set by your
I etcl
rc lIe usinl the -bd 8aa. The -bel 8aa and the
-q
flag may be combined iD one caU:
/usr/lib/sendmail -bd -q30m
3.3. Forclns the Queue
In some cases you may Ind that the queue has lotteD dOlled for lODle reason. You
can force a queue run usinl the
-q
8aa (with no value). It is eDtertaininl to use the -v
flag
(verbose) wheD this is daDe to watch what happens:
lusr/lib/seDdmail-q -v
3.4. DebuSstnS
There are a fairly large number of debul 8ap built into ,entlmtJiL Each debul 8al
has a number and a level, where higher levels means to print out more information. The
conventioD is that levels greater than Dine are "absurd," because they priDt out
BO
much
information that you wouldn't normally want
to
see them except tor debuuinl that
