PRELINE(1) Double Precision, Inc. PRELINE(1) NAME preline - Prepend legacy mbox headers SYNOPSIS /usr/local/bin/preline {program} [arg...] DESCRIPTION preline is a wrapper for program. preline is usually invoked from $HOME/.courier. preline runs program, together with any additional argu- ments specified on the command line. program then receives the message be- ing delivered, with some additional headers. The additional headers come from the UFLINE, DTLINE, and RPLINE environment variables. These environ- ment variables are initialized by courierdeliver, which reads and executes commands from $HOME/.courier. These environment variables contain addi- tional headers that should be added to every message that's delivered to a local mailbox. preline must be used if program, that is executed from $HOME/.courier to deliver mail, does not recognize these environment variables. UFLINE con- tains the From_ line, DTLINE contains the Delivered-To: header, and RPLINE contains the Return-Path: header. If these headers are not present in the message that the program reads, you may end up with excessive resources be- ing consumed by mail loops or by malfunctioning software which expects to see From_ lines in all messages scheduled for local delivery (such as proc- mail). EXAMPLE | /usr/local/bin/preline /usr/bin/procmail This is the normal way to arrange for procmail to handle local mail deliv- ery. SEE ALSO courierpop3d(8)[1], couriertcpd(8)[2], authlib(7)[3].
