The internal default is# a load average of 8 and need not be explicitly stated in the# configuration file.## Large systems (8800 class) can set this value to about 20 to 25# while small systems (uvax) should run at about 4.## The exact setting depends on processor speed, swap space, memory# size, and normal load average. The load average of your system# should be checked during a normal work period and the "x" option# set to a few degrees higher. Too low a value will cause mail to# be unneccessarily delayed, while too high a value may tend to# increase the load on the machine during transient peaks.#Ox8## Option "X" (upper case) specifies the load average at which point# sendmail will refuse further connections.# The internal default is 12. ## Large systems (8800 class) can set this at approximately 25 to 30. The# same comments apply here as for option "x" (lower case). Small systems# (uvax, small memory, limited swap space) should run at about 5 or 6.#OX12##################################   Message precedences   ##################################Pfirst-class=0Pspecial-delivery=100Pjunk=-100############################   Trusted users   ############################TrootTdaemonTuucpTnetwork################################   Format of headers   ################################H?P?Return-Path: <$g>H?R?Received: $?sfrom $s $.by $j ($v/$V)	id $i; $bH?D?Resent-Date: $aH?D?Date: $aH?F?Resent-From: $qH?F?From: $qH?x?Full-Name: $xHSubject:# HPosted-Date: $a# H?l?Received-Date: $bH?M?Resent-Message-Id: <$t.$i@$j>H?M?Message-Id: <$t.$i@$j>##############################   Rewriting rules   ###############################################################  Sender Field Pre-rewriting  #################################S1#R$*<$*>$*		$1$2$3				defocus####################################  Recipient Field Pre-rewriting  ####################################S2#R$*<$*>$*		$1$2$3				defocus##################################  Final Output Post-rewriting  ##################################S4R@			$@				handle <> error addr# resolve numeric addresses to name if possibleR$*<@[$+]>$*		$:$1<@$[[$2]$]>$3		lookup numeric addr# externalize local domain infoR$*<@LOCAL>$*		$:$1<@$A>$2			change local infoR$*<$*.LOCAL>$*		$:$1<$2.$D>$3			change local infoR$*<$+>$*		$1$2$3				defocusR@$+:$+:$+		@$1,$2:$3			<route-addr> canonicalR@$+:$+			$@<@$1:$2>			route-addr needs <># UUCP must always be presented in old formR$+@$-.UUCP		$2!$1				u@h.UUCP => h!u# Put MAIL-11 back in :: formR$+@$-.DNET		$2::$1				u@h.dnet => h::uR$+@$-.$-.DNET		$2.$3::$1			numeric form# delete duplicate local names -- mostly for arpaproto.mcR$+%$=w@$=w		$1@$3				u%UCB@UCB => u@UCBR$+%$=w@$=w.$D		$1@$3.$D			u%UCB@UCB => u@UCB############################  Name Canonicalization  ############################S3# handle "from:<>" special caseR<>			$@@				turn into magic token# basic textual canonicalizationR$*<$*<$*<$+>$*>$*>$*	$4				3-level <> nestingR$*<$*<$+>$*>$*		$3				2-level <> nestingR$*<$+>$*		$2				basic RFC821/822 parsingR$+ at $+		$1@$2				"at" -> "@" for RFC 822R$*<$*>$*		$1$2$3				in case recursive# make sure <@a,@b,@c:user@d> syntax is easy to parse -- undone laterR@$+,$+			@$1:$2				change all "," to ":"# localize and dispose of domain-based addressesR@$+:$+			$@$>6<@$1>:$2			handle <route-addr># more miscellaneous cleanupR$=w::$-$+		$2$3				clean off my nameR$+			$:$>8$1				host dependent cleanupR$+:$*;@$+		$@$1:$2;@$3			list syntaxR$+@$+			$:$1<@$2>			focus on domainR$+<$+@$+>		$1$2<@$3>			move gaze rightR$+<@$+%$+>		$1%$2<@$3>			move gaze rightR$-!$+<@$~S>		$1!$2@$3			defocus - not local hostR$-::$+<@$~S>		$1::$2@$3			defocus - not local hostR$+<@$+>		$@$>6$1<@$2>			already canonical# localize mail-11 syntaxR$-::$+			$@$>6$2<@$1.dnet>		host::userR$-.$-::$+		$@$>6$3<@$1.$2.dnet>		numeric decnet addr# convert old-style addresses to a domain-based addressR$+%$+			$:$1<@$2>			user%hostR$+<@$+%$+>		$1%$2<@$3>			move "@" rightR$+<@$+>		$@$>6$1<@$2>			now canonicalR$-:$+			$@$>6$2<@$1>			host:userR$-.$+!$+		$@$>6$3<@$1.$2>			host.domain!userR$-!$+			$@$>6$2<@$1.UUCP>		resolve uucp names
