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
