Sending a large mail with Mail::sendMail

mrguy123 has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks
I am writting a program that sends a mail when it is done, with a list of failed resources as output (part of a metasearch engine)
For this I am using the module Mail::SendMail
This the code

#!/exlibris/metalib/m4_b/product/bin/perl
BEGIN {
    unshift (@INC, $ENV{'alephm_source'}.'/com_perl');
}
use Mail::Sendmail;
my $email ='guy.naamati@exlibris.co.il';
my $from ='guy.naamati@exlibris.co.il';
my $subject='test email';
my $message='';
my $file = "";

my $message = 'institution Name: METALIB
No. of tested resources: 52
No. of failed searches (0 results or errors in all attempts): 49

    my %mail=(

        File    => $file,
        Subject => $subject,
        Message => $message
    );
    my $return = Mail::Sendmail::sendmail(%mail);
    $error = $Mail::Sendmail::error;
    $log   = $Mail::Sendmail::log;

    #print "return=$return\n";
    #print "error =$error\n";
    print "log=$log\n";

This works great for short messages, but when the message is long (as in the example), the mail isn't sent. I looked at the log and the error message returned, but couldn't find anything. I also tried to send the long mail in Net::SMTP but with no success.
If I delete most of the message, the mail is sent. Does anyone know what the problem with the large message is?
Much obliged

I also tried to send the long mail in Net::SMTP but with no success. I don't know that other module at all, but if you used Net::SMTP, then you should know precisely why it didn't work!! `my $smtp = Net::SMTP->new($server, Hello=>"dude!", Timeout=>20, Debug= +>1) or die; # Debug makes Net::SMTP spew the session to your STDERR.` [download] If you need assistance with the output, I can help, but it should be pretty clear what's going wrong. -Paul	[reply] [d/l]

thanks for the advice I did have the debug mode on, but with didn't find any usefull info. I will try sending the mail to a different acount (like the other guys suggested), and if that doesn't work, I will try looking at the log again Thanks again Guy	[reply]

...debug mode on, but with didn't find any usefull info... I find that rather hard to believe. Either there was actually useful info there or the mail system accepted the message for delivery. If it was accepted, then you need to ask your mail systems administrator why the system is silently discarding those messages ... and no amount of perl magic will save you from that fate. -Paul	[reply]

You could be using a here-doc to 'wrap' a multiline text in a single string, i.e. `my $message = <<'EOT'; institution Name: METALIB [...] EOT` [download] Use `<<"EOT"` if you wish for variables to be interpolated. `EOT` can surely be named otherwise, as long as it is consistent (as in, start of here-doc (`<<'EOT'`) & end of here-doc (`EOT`) share both the same 'identifier' and the ending identifier is placed on a single, ending line). Have you verified the string didn't get accidentally truncated before handing it over to `sendmail()`? If it didn't, would you care to paste the output of `$Mail::Sendmail::error` and `$Mail::Sendmail::log`?	[reply] [d/l] [select]

This is the log: `log=Mail::Sendmail v. 0.78 - Sun May 20 13:40:53 2007 Date: Sun, 20 May 2007 13:40 +0300 Server: localhost Port: 25 From: guy.naamati@exlibris.co.il Subject: test email To: guy.naamati@exlibris.co.il` [download]	[reply] [d/l]

The log looks okay to me. There is the possibility that Sendmail is rejecting your mail due to a too large message body in size. You might want to check whether 'root' did receive some according bounces (see `/var/mail/root, /var/spool/mail/root, etc.`). Can you verify that?	[reply] [d/l]
