NAME
Mail::Qmail::Queue::Receive::Body - Receive message body when emulating qmail-queue
SYNOPSIS
use Mail::Qmail::Queue::Receive::Body;
my $qq_body = Mail::Qmail::Queue::Receive::Body->new
or die "Couldn't get qmail-queue body\n"
print "Message body: ",$qq_body->body,"\n";
my $fh = $qq_body->body_fh
or die "Error getting body handle: $!\n";
while (<$fh>) {
s/perl/Pathologically Eclectic Rubbish Lister/gi;
print;
}
$fh->close
or die "Error closing message: $!\n";
DESCRIPTION
Mail::Qmail::Queue::Receive::Body
is designed for use in qmail-queue
emulation. This is a way of modifying the behavior of qmail by replacing its queueing mechanism with your own program, which may modify or reject the message, then call the real qmail-queue
program to queue the message. This is commonly done with Bruce Guenter's QMAILQUEUE patch (http://www.qmail.org/top.html#qmailqueue), also included in netqmail (http://www.qmail.org/netqmail/). This patch lets you override the standard qmail-queue
program by setting the environment variable QMAILQUEUE
. It can also be done by renaming the original qmail-queue
, installing your script in its place, and having your script call the renamed qmail-queue
to inject the message.
For a simplified interface, see Mail::Qmail::Queue::Message. To read the message envelope, see Mail::Qmail::Queue::Receive::Envelope. To re-inject the message, see Mail::Qmail::Queue::Send.
Note that the specifications for qmail-queue
's interface require that the message be read before the envelope.
The constructor and methods of this class will die
if they encounter a serious error. If you would prefer different behavior, use eval
to catch these and handle them as exceptions.
CONSTRUCTOR
- new ( %options )
-
Creates a new qmail-queue message body reader, but does not start reading it.
Available options are:
- FileHandle
-
Read the body from the specified file handle, instead of the default of file desriptor 0.
METHODS
- body_fh( )
-
Returns a filehandle from which the body can be read.
- close( )
-
Closes the filehandle with the message body, and returns the result of the
close
. - body( )
-
Returns the entire body as a string, then closes the filehandle. Note that this can consume a lot of memory for a very large message; reading it from the handle returned by the
body_fh
method will be more efficient.
