Resend emails from a Maildir

[Patric Falinder]

Hi,

I'm not really sure if this has to do with Postifx so just tell me if
I'm wrong.

Is it possible to resend emails that are in a Maildir already?
The reason for this is that a user changed server so I had to change the
transport for that domain and there are something like 50 mails in the
old Maildir that I need to "resend" to the new server.

Is that possible?


Thanks,

Yes.

#!/bin/sh

#
# verschickt die gesamte Mail eines Benutzers an $1
#
USAGE="usage: $0 ***@domain"

if test $# != 1
then
echo $USAGE
exit 1
fi

if ! grep @ <<STOP > /dev/null
$1
STOP
then
echo $USAGE
echo No @ in Mail-address
exit 1
fi

if ! test -d new -a -d cur -a tmp
then
echo You are not in Maildir
echo there is no new cur tmp
exit 1
fi


find cur new tmp -type f | xargs --replace /usr/local/scripts/send_mail $1 {}

Now that's interesting construct ;)

case "$1" in
?*@?*) ;;
*) echo "No @ in Mail-address" >&2; exit 1;;

if it's maildir at both sides, the simple thing is to copy the files
(cp, scp, rync, ... etc.)

if you believe smtp is the right transport, then:
- you'll need to make sure the "Delivered-To" header does not match the
next destination address (otherwise, Mr postfix will "think" this is a loop)
- get the MAIL FROM address from the "Return-Path" header. with this you
can do: sendmail -f $returnpath yourdestinationemail

Make that:

sendmail -i -f "$returnpath" -- "$destpath" < msgfile

The returnpath can have all kinds of interesting characters. If using
Perl, it is highly advisable to entirely bypass shell argument parsing:

$prog = "/usr/sbin/sendmail";
@rcpts = ( q{***@example.com} );
@args = qw(sendmail -i);
push(@args, "-f", "$envsender");
push(@args, "--", @rcpts);
system { $prog } @args;
if (($code = $?) ne 0) {
# handle errors
}

indeed.

If using
$prog = "/usr/sbin/sendmail";
@rcpts = ( q{***@example.com} );
@args = qw(sendmail -i);
if (($code = $?) ne 0) {
# handle errors
