NAME
qmail-newmrh - prepare morercpthosts for qmail-smtpd SYNOPSIS
qmail-newmrh DESCRIPTION
qmail-newmrh reads the instructions in /var/lib/qmail/control/morercpthosts and writes them into /var/lib/qmail/control/morercpthosts.cdb in a binary format suited for quick access by qmail-smtpd. If there is a problem with control/morercpthosts, qmail-newmrh complains and leaves control/morercpthosts.cdb alone. qmail-newmrh ensures that control/morercpthosts.cdb is updated atomically, so qmail-smtpd never has to wait for qmail-newmrh to finish. However, qmail-newmrh makes no attempt to protect against two simultaneous updates of control/morercpthosts.cdb. The binary control/morercpthosts.cdb format is portable across machines. SEE ALSO

NAME
qmail-control - qmail configuration files INTRODUCTION
You can change the behavior of the qmail system by modifying qmail's control files in /var/lib/qmail/control. qmail can survive with just one control file, me, containing the fully-qualified name of the current host. This file is used as the default for other hostname-related control files. Comments are allowed in badmailfrom, locals, percenthack, qmqpservers, rcpthosts, smtproutes, and virtualdomains. Trailing spaces and tabs are allowed in any control file. The following table lists all control files other than me. See the corresponding man pages for further details. control default used by badmailfrom (none) qmail-smtpd bouncefrom MAILER-DAEMON qmail-send bouncehost me qmail-send concurrencylocal 10 qmail-send concurrencyremote 20 qmail-send defaultdomain me qmail-inject defaulthost me qmail-inject databytes 0 qmail-smtpd doublebouncehost me qmail-send doublebounceto postmaster qmail-send envnoathost me qmail-send helohost me qmail-remote idhost me qmail-inject localiphost me qmail-smtpd locals me qmail-send morercpthosts (none) qmail-smtpd percenthack (none) qmail-send plusdomain me qmail-inject qmqpservers (none) qmail-qmqpc queuelifetime 604800 qmail-send rcpthosts (none) qmail-smtpd smtpgreeting me qmail-smtpd smtproutes (none) qmail-remote timeoutconnect 60 qmail-remote timeoutremote 1200 qmail-remote timeoutsmtpd 1200 qmail-smtpd virtualdomains (none) qmail-send SEE ALSO
