I am trying to send an email via a Java Servlet and am getting this error: DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc] DEBUG SMTP: useEhlo true, useAuth false DEBUG: SMTPTransport trying to connect to host "localhost", port 25 DEBUG SMTP RCVD: 220 TVS-web ESMTP Sendmail 8.9.3/8.9.3; Fri, 26 Oct 2001 23:09:50 -0700 DEBUG: SMTPTransport connected to host "localhost", port: 25 DEBUG SMTP SENT: EHLO DEBUG SMTP RCVD: 501 EHLO requires domain address DEBUG SMTP SENT: HELO DEBUG SMTP RCVD: 501 HELO requires domain address Of course there are other Java exceptions, but I am not including those, I am using JavaMail. I assume this is a sendmail configuration error. Thanks for any help. Erick
