Re: Need psql send email

many is the time when spammers have used Open Relay SMTP servers to send their junk mail so i would advise against using sendmail on Open Relay SMTP servers
I would narrow access by SSH or open a secure tunnel thru your firewall to your own internal DatabaseManagementSystem/J2EEServer/ApacheHTTPServer then allow
those scripts (PL-SQL or Perl or Java) to invoke sendmail to the SMTPMailServer inside the firewall

If you are sponsoring your own email-server and I hope you are DISALLOW OPEN RELAY

Alternatively:


CREATE OR REPLACE FUNCTION sendmail(p_from text, p_to text, p_subject text, p_content text)
  RETURNS void AS
$BODY$
use strict;
use warnings;
my ($from, $to, $subject, $content) = @_;
 
open(MAIL, "|/usr/sbin/sendmail -t") or die 'Cannot send mail';
print MAIL "From: $from\n";
print MAIL "To: $to\n";
print MAIL "Subject: $subject\n\n";
print MAIL "$content";
 
close(MAIL);
$BODY$
  LANGUAGE plperlu;


Works ok provided sendmail is configured.

or:

CREATE OR REPLACE FUNCTION send_smtp(p_mail_host text,
                                        p_from text,
                                        p_to text,
                                        p_subject text,
                                        p_content text,
                                        p_timeout integer DEFAULT 60,
                                        p_debug integer DEFAULT 0,
                                        p_exactaddr integer DEFAULT 1,
                                        p_skipbad integer DEFAULT 1)
  RETURNS void AS
$BODY$
use strict;
use warnings;
use Net::SMTP;
no strict 'refs';

my ($host, $sender, $recipient, $subject, $body, $timeout, $debug, $exact, $skipbad) = @_;
(!defined($host) || !($host)) && die 'No SMTP host provided.';
(!defined($sender) || !($sender)) &&  die 'No sender address/name provided.';
(!defined($recipient) || !($recipient)) &&  die 'No recipient address specified.';

my $mail = Net::SMTP->new(
                                Host => $host,
                                Debug => $debug,
                                Timeout => $timeout,
                                ExactAddresses => $exact
                        ) or die 'Net::SMTP->new() Failed';

$mail->mail($sender);
$mail->recipient($recipient, { SkipBad => $skipbad });

$mail->data();
$mail->datasend("MIME-Version: 1.0\n");
$mail->datasend("From:" . $sender . "\n");
$mail->datasend("To:" . $recipient . "\n");
$mail->datasend("Reply-To: ". $sender . "\n");
$mail->datasend("Subject:" . $subject . "\n\n");
$mail->dataend();
$mail->quit();
$BODY$
  LANGUAGE plperlu;


Feel free to hack away as much as required.

Both of these work fine provided PL/PerlU is installed and the server is properly configured on the network, and that there is a valid SMTP mail host to receive.


Cheers
