NAME

       cancelmsg - Cancel an E-mail message

SYNOPSIS

       cancelmsg {msgid} ["reason"]

DESCRIPTION

       cancelmsg removes a message from the mail queue. There will be no more attempts to deliver this message, and a standard delivery failure
       notice is sent to the return address listed on the message. You can only cancel your own messages. The superuser can cancel any message. An
       attempt to cancel a message will fail if the message has already been sent (of course), or if a delivery attempt is currently in progress.
       Because a delivery attempt is usually started as soon as an E-mail message is added to the mail queue, a cancellation attempt is only
       effective if the message cannot be immediately delivered for some reason, or if the system is very busy and is working on a mail backlog.
       cancelmsg works by marking all pending recipients as undeliverable. A non-delivery report is then generated and sent in the normal fashion.

       msgid is the message queue id that can be obtained from the mailq(1)[1], command. A reason is optional. The message does not disappear into
       a black void. The message will be returned as undeliverable, citing reason. A generic error message will be used if reason is not
       specified.

BUGS

       A non-delivery report may not be sent immediately, but delayed until the message's turn comes up in the scheduling queue.

       There is no immediate indication if the message cancellation worked. A subsequent non-delivery report is the only indication of a
       successful cancel. If it doesn't come, it means the message wasn't cancelled in time.

       A non-delivery report will not be sent for recipients whose delivery status notification does not include the FAIL notice.

NAME

       makepercentrelay - Build a list of %-relayed domains

SYNOPSIS

       makepercentrelay

DESCRIPTION

       makepercentrelay reads /etc/courier/esmtppercentrelay.dir and creates /etc/courier/esmtppercentrelay.dat which is a binary database file.
       The files /etc/courier/esmtppercentrelay and /etc/courier/esmtppercentrelay.dat specify a list of "percent-hack" domains.
       /etc/courier/esmtppercentrelay is a plain text file, containing one domain per line. The Courier mail server loads the contents of
       /etc/courier/esmtppercentrelay into memory, so if you have a lot of domains, you will want to use the binary database file. The
       makepercentrelay command reads /etc/courier/esmtppercentrelay.dir, which can be either a plain text file itself, or a directory containing
       plain text files. All files in the subdirectory are concatenated, and the binary database file is created from the result.

       the Courier mail server can use both /etc/courier/esmtppercentrelay and /etc/courier/esmtppercentrelay.dat at the same time. Usually you
       would put a couple of your most frequent domains in /etc/courier/esmtppercentrelay, then put the rest in
       /etc/courier/esmtppercentrelay.dir, and use makepercentrelay to turn it into a database file.

       "percent-hack" domains are a list of domains for which the Courier mail server accepts mail via ESMTP addressed as
       "local%percent.hack.domain@local.domain", where "percent.hack.domain" is a domain found in /etc/courier/esmtppercentrelay or
       /etc/courier/esmtppercentrelay.dat, and "local.domain" is any domain found in /etc/courier/locals. The Courier mail server removes the
       local domain, and rewrites the address as "local@percent.hack.domain", then attempts to deliver it.

       The percent hack applies only to mail received via ESMTP. The Courier mail server does not check this list of domains if the message is
       received via any other way (such as by running /usr/bin/sendmail directly from the command line). "percent.hack.domain" would likely to be
       a domain that the Courier mail server knows how to handle via some other means. It might be an entry in /etc/courier/aliases, or an entry
       in /etc/courier/esmtproutes.
