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 Martin Gainty ______________________________________________ Verzicht und Vertraulichkeitanmerkung/Note de déni et de confidentialité Diese Nachricht ist vertraulich.

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.
