howto send a mail with attachment via perl script ?

cccc · 02-24-2004, 06:52 PM

hi

in my perl script I write the log with

BEGIN
{
use CGI::Carp qw(carpout);
my $errorlog = "/var/errorlog.txt";
open(LOG, ">$errorlog") or die("Unable to open $errorlog: $!\n");
print LOG "Errors:\n";
carpout(*LOG);
}

and transfer 2 file via ftp

.............................................................................................
.............................................................................................
my $ftp = Net::FTP->new ($server, Timeout => 9000, Debug => 3);
$ftp or die "$server: cannot connect: $@";
# If you don't use ~/.netrc
$ftp->login ('anonymous', 'mail@domain.net') or
die "$_: cannot logon: " . $ftp->message;

# Put file 2 (not 1) to the ftp server
$ftp->put ($f2) or
die "$server: cannot put $f2: " . $ftp->message;

$ftp->quit;

# wait for 10 seconds
sleep (1 * 10);
}

but how to send the mail on the end with the log file errorlog.txt as attachment,
when the transfer was successfully completed ?

I think something like this:

open(MAIL, "|/usr/sbin/sendmail -t");
print MAIL "to:$mail\n";
print MAIL "from:$linux\n";
print MAIL "subject:ftp transfer was successfully \n";

print MAIL "------------------------------------------------------------------\n";

print MAIL "ftp transfer was successfully\n\n";

print MAIL "Time: ". localtime(time) ." \n";

print MAIL "------------------------------------------------------------------\n";

Attachment ?

close(MAIL);
}

kind regards

The best way to see it is to read the source of a message in your inbox that has an attachment. The trick is to use multipart boundaries. Here is a cut down example from an e-mail sent to me:

Code:

From: xyz@host.com
To: xyz@host.com
Subject: Some subject
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="----=_NextPart_000_002F_01C3F989.5E1B7780"


------=_NextPart_001_0030_01C3F989.5E1B7780
Content-Type: text/plain;
Content-Transfer-Encoding: quoted-printable

This is the message text

below is the binary content of a jpg in a new multipart section

------=_NextPart_000_002F_01C3F989.5E1B7780
Content-Type: image/jpeg; name="file.jpg"
Content-Disposition: attachment; filename="file.jpg"
Content-Transfer-Encoding: base64

thanks

but how will be the perl code, if I can ask you
to read to read the source from /var/errorlog.txt ?

Code:

open(FILE, "/var/errorlog.txt");
$content=<FILE>;
close(FILE);

open(MAIL, "|/usr/sbin/sendmail -t");
print MAIL <<"EOF";

To: xyz\@host.com

hallo david_ross

I've tried this but wont work:

open(FILE, "/var/errorlog.txt");
$content=<FILE>;
close(FILE);

open(MAIL, "|/usr/sbin/sendmail -t");
print MAIL <<"EOF";
From:root\@domain.net
To:xxx\@domain.net
Subject: transfer was successfully !

hi,

transfer was successfully !

$content

Time: ", scalar localtime,

EOF

close(MAIL);

I get error mesage for 2 lines:

$content=<FILE>;

" Global symbol "$content" requires explicit package name "

and

$content

" Global symbol "$content" requires explicit package name "

At CPAN there is a module that does just what you need: Net-SMTP-Multipart-1.5.tar.gz

It relies on Net::SMTP and Mime::Base64. Be sure to read the POD it tells you how to use it for just what you asked for. The location is: http://www.cpan.org/authors/id/D/DR/...art-1.5.tar.gz

cccc · 02-26-2004, 05:44 PM

but this way from david_ross should work also
and I want to know what's wrong.

I would suggest you use MIME::Lite (found on CPAN) - it's really easy and straight forward. Below is the sub I use to send a contact card. (I use qmail as a mail server - but it should make sense.)

use strict;
use MIME::Lite;

sub sendEmail {
my $name = $_[0];
my $from = $_[1];
my $to = $_[2];
my $subject = $_[3];
my $body = "Please see the attached.";

my $injector = "/var/qmail/bin/qmail-inject";

open (MESSAGE, "| $injector -f '$from' '$to'") or erp("> Can't open $injector!\n");

my $msg;
$msg = MIME::Lite -> new(
From => "$name <$from>",
To => "$to",
Subject => "$subject",
Type => "multipart/mixed"
);

$msg -> attach(
Type => "text/html",
Data => "$body"
);

$msg -> attach(
Type => "text/x-vcard",
Path => "/usr/local/apache/vcard.vcf",
Filename => "info.vcf",
Disposition => "attachment"
);

$msg -> print(\*MESSAGE);
close (MESSAGE);
}

Well basically it ought to work. Here is my test script:

#!/usr/bin/perl

$localtime = localtime();
open(FILE,"/var/log/dmesg");
$content = <FILE>;
open(MAIL, "| cat > foo.txt");

print MAIL << "EOF";
From: dford
To: dford
Subject: Successful

Hi!
$content

Time: $localtime

EOF
exit;

And my results are:

From: dford
To: dford
Subject: Successful

Hi!
Linux version 2.4.20-28.9 (bhcompile@porky.devel.redhat.com) (gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 Thu Dec 18 13:45:22 EST 2003

Time: Thu Feb 26 21:36:20 2004

So, what else is in your script?

cccc · 02-29-2004, 06:57 PM

hi dford

and where should I put the path to sendmail on your script ?

kind regards
cccc

dford · 03-01-2004, 02:28 PM

My script was just a quick hack test. Where I had:

Code:

open(MAIL, "| cat > foo.txt");

You should replace that with david_ross's:

Code:

open(MAIL, "|/usr/sbin/sendmail -t");

You also should probably add:

Code:

close(MAIL);

before the exit; as well.

hi

I have a script , NO ERRORS, but NO MAILS !

knows someone what's wrong ?

Code:

#!/usr/bin/perl -w
use MIME::Lite;
use Getopt::Std;
use Net::SMTP;

my $SMTP_SERVER = '/usr/sbin/sendmail -t';
my $DEFAULT_SENDER = 'sender@domain.net';
my $DEFAULT_RECIPIENT = 'recipient@domain.net';

MIME::Lite->send('sendmail', $SMTP_SERVER, Timeout=>60);

my (%o, $msg);

# process options
getopts('hf:t:s:', \%o);

$o{f} ||= $DEFAULT_SENDER;
$o{t} ||= $DEFAULT_RECIPIENT;
$o{s} ||= 'attachment';

if ($o{h} or !@ARGV) {
die "usage:\n\t$0 -h -f -t -s /var/log/log.txt\n";
}

# construct and send email
$msg = new MIME::Lite(
From => $o{f},
To => $o{t},
Subject => $o{s},
Data => "Hi",
Type => "multipart/mixed",
);

while (@ARGV) {
$msg->attach('Type' => 'application/octet-stream',
'Encoding' => 'base64',
'Path' => shift @ARGV);
}

kind regards
cccc

dford · 03-03-2004, 08:32 PM

It looks like you just need to add

Code:

$msg->send();

to the end.

cccc · 03-04-2004, 04:44 AM

hi dford

I've added.
but still NO mails !

kind regards
cccc

dford · 03-04-2004, 09:58 AM

Okay here is the script I used, basically the script you had:

Code:

#!/opt/perl/bin/perl -w
use MIME::Lite;
use Getopt::Std;
use Net::SMTP;

my $SMTP_SERVER = '/usr/sbin/sendmail -t';
my $DEFAULT_SENDER = 'dford@tacsea.metapath.com';
my $DEFAULT_RECIPIENT = 'don.ford@metapath.com';

my (%o, $msg);

# process options
getopts('hf:t:s:', \%o);

$o{f} ||= $DEFAULT_SENDER;
$o{t} ||= $DEFAULT_RECIPIENT;
$o{s} ||= 'attachment';

if ($o{h} or !@ARGV) {
die "usage:\n\t$0 -h -f -t -s /var/log/log.txt\n";
}

# construct and send email
$msg = new MIME::Lite(
From => $o{f},
To => $o{t},
Subject => $o{s},
Data => "Hi",
Type => "multipart/mixed",
);

while (@ARGV) {
$msg->attach('Type' => 'application/octet-stream',
'Encoding' => 'base64',
'Path' => shift @ARGV);
}

$msg->send;

I did not see the "Hi", but otherwise this worked fine. (I did change the email addresses to reduce spam potential.) I did have some issues with a bad To email address at first, but you should see the bounce messages in your mail box on the machine. I wonder if you are having issues with sendmail?
